That woukd be awesome, but as you say, Blizzard are not big on announcing dates. Not that it would mean anything anyway. If they come out tomorrow and say Fall 2011, I'm not sure I'd believe it. They wouldn't be lying of course, they just wouldn't hit it.
Hey all, a bit late notice I know, but I thought I'd see if any Giantbomb folks would be around Blizzcon this weekend. I'm rarely out on the West (best?) coast and I'm sure there's a few of you out there. Maybe we can get together and discuss how awesome we are.
The convention centre provides plenty of large Blizzard themed banners that can act as meeting places. Failing that, I'll be watching a lot of the Starcraft 2 tourney stuff.
