I just saw a video of BB10 in action and was wowed by just the little bit I watched. The functionality is amazing. The soft-keyboard does more than any other KB I've seen. The integration of swipe panels is sweet.
Sheeesh! I can't wait for this to hit my PB and for BB10 hardware to be released. Depending on the actual hardware aesthetics and features, BB10 has the possibility to blow all other systems away.
