Yeap, cause everything ends up on BluRay, no wait, it doesn't.
FCP is for editing, Motion is for graphics, Soundtrack Pro is for audio, Compressor is for encoding (even for BluRay) and Color is for grading.
If you need to author BluRay you use another tool.
Also there will be no training of the new software at NAB, why because NAB is almost over by Tuesday night. Most of the training will already have happened. And there is always a lot of training going on, there are classes to get certified, and certified instructors do not get advanced copies of the software.
Also I don't see Apple hijacking the SuperMeet, those guys would not screw all their long time sponsors for a one time apple thing. This event is huge, they have everything. Now there might be some re-shifting but as I said Tuesday is a long time to hold something through NAB. Apple used to have there own major event on Sunday mornings to unveil the newest FCP.
