Yeah, aside from teh crazy announcing and overuse of the word "technology", that control point warp isn't new. It already had it in Adobe After Effects and various animation software, and who knows where else. Nice to see it in photoshop though, I could see myself using it.
As for the brushes stuff... Weird. Enhanced smudge tool but also real simulation of brush tips? Could be interesting, but it's not high on my list of things I think Adobe labs should be working on.
Something like this is far more interesting. Also CS5
