I think there’s a 100% chance. There’s already a 100% chance, if you’re willing to tether the camera to a laptop or desktop — you can use FCP-HD or Avid Express HD or Canopus Edius and capture straight from the firewire, with no need to have a P2 card at all.
And, Serious Magic’s already working with Panasonic to try to get an HVX-compatible version of DV Rack out there.
But for on-camera: at the bare minimum you’ll have direct-to-disk from FireStore. There may be other options as well.

Direct to disk will likely surface before the release of the camera; Focus is already a P2 partner and apparently hard at work on an HVX-compatible FireStore. And Serious Magic is already talking with Panasonic about making DV Rack compatible with the HVX.

1.85 would amount to 2% off the top and bottom — not enough to even be concerned about.
2.39 would be cool.

The answer is: if you’re editing on a 24P timeline, shoot 24PA (2:3:3:2). If you’re editing on a 60i timeline, shoot 24P (2:3).

Interesting idea. That Extreme III CF card looks like it might have enough sustained read/write speed to support DVCPRO-HD as well.
At this time I have no idea what level of controller circuitry is on a P2 card — we know at the bare minimum that it has a RAID controller to process dividing the workload across four SD cards. And the transfer rate is much, much higher on a P2 card — 80 megabytes per second, vs. 20 on that fastest CF card. That may or may not have any effect on direct writing speed, but it’ll certainly have an effect on transfer speed when offloading the card.
Obviously it looks like it’s worth a try — anyone here have an SPX800 we could experiment on? 😀

[toke lahti] “Btw, jvc is advertizing hd-sdi option to it’s 100.
Does anybody have a clue will that mean really 10bit uncompressed or just some lame fw-sdi converter? “
There is no access to the uncompressed digital signal. So the only way to get HD-SDI is to use either some sort of converter from the firewire, or to convert from the analog outputs. At NAB they were demonstrating HD-SDI, I asked ’em about it and asked if there was an option board, and the guy said “well, no, we’re using this AJA converter hooked to the analog component outputs.”That doesn’t mean it won’t look good, that just means it’s not going to be an HD-SDI signal direct from the camera head, it’s going to be a digitized version of the analog outputs.

[Graeme Nattress] “Look at all the bother we’ve had with the introduction of the new HDV codec, and now JVC threw a spanner in the works with their 24p mode that nobody is supporting yet (save 3rd party vendors like LumiereHD) because they, the NLE people, have only just got normal HDV “working”. “
Well, “working” is also a relative term. Because when you’re talking about ProHD/HDV, you’re actually talking about three relatively incompatible formats.
It turns out that the JVC implementation of HDV, and the Sony implementation of HDV, are excluding support for the other at the firewire level. What this means is, if you’re a JVC shooter, and someone hires you to shoot some HDV for them, and you deliver them a tape, and they happen to have Sony gear — the tape you hand them is useless. They will not be able to digitize it.
Sony offers HDV cameras and decks that say HDV on them, but if you put a JVC HDV tape in there, you will not be able to play the data through the firewire nor capture it. You have no access to the footage (other than to play it on a television and watch what you cannot digitize).
And, JVC offers cameras and decks that feature the same HDV logo — but if a Sony shooter gives you a tape, you will not be able to play that on your JVC equipment and digitize it.
If you like the Sony HDV, but prefer the JVC HDV deck because it can take large cassette sizes… um, don’t do it. That deck will never be able to play back your camera’s tapes so that you can digitize them.
The formats are mutually exclusive, when it comes to digitizing. The editing programs can support both formats, yes; but the playback equipment cannot.
A JVC HDV deck can play back JVC HDV to firewire, but cannot play back Sony HDV or ProHD tapes to firewire. A JVC ProHD deck can play back JVC HDV or ProHD to firewire, but cannot play back Sony HDV to firewire. A Sony HDV deck can play back Sony HDV, but cannot play back ProHD or JVC HDV to firewire.
I guess what I’m saying is — don’t necessarily go assuming that HDV is a standard, it’s actually currently about three fairly incompatible, mutually-exclusive standards. If you’re planning on getting an HDV camera so you can shoot for HDV post houses, you better check with them as to what gear they support, because the Sony and JVC implementations are mutually exclusive when it comes time to digitize. Either that, or every post house is going to have to buy at least two decks so they can support both flavors.
For customer confusion purposes, it probably would have been better if they hadn’t lumped both formats under the HDV banner.

P2 cards have been in the field for over a year now. The laptop system works. Backing up is always wise, yes, but this is a proven workflow already.

[toke lahti] “But if dv and dvcpro25 are identical in p2, what’s stopping you to export dv from p2 to dvcprotape to be as dvcpro25?”
Nothing — provided you’re in NTSC mode. The bitstream is identical, so you could execute a firewire dub from DV to DVCPRO25 tape.
If you’re in PAL, you’ll have a problem, as PAL DV is 4:2:0 and PAL DVCPRO25 is 4:1:1, so you couldn’t do a firewire dub of that.

[Rodrigo Lizana] “I really like to know (a good technical reason) why this camera is going to add the pulldown to the 1080p24 mode instead of using all the 100 mb/s bandwidth on the 24 frames per second. “
Because DVCPRO-HD uses a fixed data rate per frame. It’s not variable-bitrate, it allocates exactly the same bitrate to every frame. It’s not 100 megabits per second, it’s more like 3.34 megabits per frame 1080 frame.
That’s why 720/24p takes up 40 megabits, rather than being spread across 100. It’s the very nature of the fixed-bitrate, constant-bitrate, intraframe-only compression that lets DVCPRO-HD work as well as it does (no GOP, instant edit, edit-ready, preview through firewire, no variable-resolution issues on panning, etc).
