I have heard rumors for a while about QT6 and some of it's new features (MPEG4 is the big one!) Like Divx for the PC, but using standards. Real is also on board with the MPEG4 standard. I can't wait.
Apple really needs to promote this version of QuickTime like they have iTunes, iMovie, and now iPhoto. If they can get MPEG4 to the point where you really can't tell the difference between it and MPEG2, with very small file sizes, Apple could be on the brink of something amazing (once again)
I only hope it comes out... To have VHS+ quality movies @ < 600MB would be great. But at
www.quicktime.com they still say version 5 is new...
