I think what everyone is forgetting is that these are SNEAKS. Sneaks mean, "we're showing you something that we're developing and something that MIGHT be in a future product" (no promises).
So if the technology isn't completely done, or they show an example of what it might do when completed, I don't have a problem with that. They're not trying to sell it to me now. They're just showing what they're working on. And knowing Adobe, they'll get it perfected before another version of Photoshop is released (or whenever).
Making a huge deal about this is simply silly—it's a "sneak". But maybe it's just me. ;)
