I said this in another thread and I'll say it again here: He was specifically and intentionally asked about Aperture 3.5. This was not a mistake; it has the approval of Apple PR all over it. Nowhere has he said that what was shown in the video was Aperture 4 or 3.5.
I'm not saying Aperture 4 actually exists; I have no idea. But it is clear that Aperture is not dead; there's no way Apple would give any version of it this much spotlight if that were the case. It's a matter of when, not if. It will come, randomly and quietly.
Completely agree that aperture is not dead - I certainly wasn't trying to suggest that it was. The continued updates show that Apple are committed to the software.
I saw your post on the previous thread, although I'd already made my post above before that other thread began. My intention was not to suggest there's no chance that Aperture 4 will come out in the near future - I'm just remaining realistic about what was actually said both by Phil Schiller at the event, and by the photographer in the interview.
Cheers
