The other features are like potential eye candy, though i am sure that there will be times I will want to use them, sparingly, to help me present my point. Look at all the bad Flash sites. Flash export will be cool given that it might really cut the quicktime size down to a bare minimum. If it is, that's quite a benefit but what about being able to preload that movie.
Most intro movies require a preloader.
This is great news for anyone who is used to easily previewing video in DV NLEs.
