Actually, it's quite possible that much of what we think of as Quicktime will go away in OSX 10.7.
Apple has tried modernizing Quicktime with something called QTKit/Quicktime X. iOS did away with this altogether and instead uses something called AVFoundation. OSX 10.7 includes an OSX version of AVFoundation.
It's not 100% clear to me what the relationship between the two on OSX will be, but I'm guessing that Apple has given up on modernizing Quicktime and is just replacing it with AVFoundation.
This can't really come quickly enough. If Windows users are tired of Quicktime, well... it behaves a lot better on OSX if you're an end-user, but programming for Quicktime is a pain. In particular, programming codec plug-ins is horrible. The basic Quicktime architecture still deals with FSSpecs, memory handles, the old Component Manager, and API artifacts relating to the old code fragment manager from the pre-OSX days. Quicktime is probably the one big chunk of code in OSX that still dates from pre-OSX days and hasn't been re-implemented in terms of something more modern like Core Foundation.
