Wait!
Cs 5.5 is nice, but needs improvements!
A word to fcp 7: I had switched to premiere pro, because if you want to work with long GOP formats like xdcam hd 422, fcp is not reliable at all! I have to switch all the pictos off and still it’s a matter of time untill I have the next crash. So: fcp might do its job for some, I had waited for years for the improvements and woke up with fcpx. So as prp in its state right now isn’t an improvement, cs 6 might be – or avid.
The nice side effect of the switcher-offers: the creative suit with ps and ae and encoder really is worth its price!
