This is an extremely painful thought, but if you wait ’til April to buy your HVX, you might get closer to a street price and the CinePorter CP-2 might be available by then. Sounds like the Cineporter’s gonna be sweet. Camera sees it as a huge P2 card, it might only record active frames, and you can plug it in directly to your laptop and transfer files (with metadata! Can’t get that through firewire.
Then again, if you’re making money with your camera now and HD is an absolute necessity, buy the camera and P2 now. It’s not a big investment for a business.
