Heard about MIX yet?  It is a Microsoft conference in Vegas focused on the "next" web  -- should be good.  I'll be there with some great new never-before-seen WPF demos and lots of folks I work closely with, including non-Microsoft folks like Darren David (who did the North Face prototype) from Fluid and Andrew Whiddett (who did the Netflix prototype) from REZN8, will also be there. Ping me if you'll be there and would like to meet up.  There's already talk of an ad-hoc BOF type Expression tools meet up -- if I find out more about when/where that will be, I'll let folks know.
