I played the XBox 360 demo of Blue Dragon tonight. It's much better than I had anticipated. Innovative combat system -- you can even fight as you wander about the map, at least a bit -- and the "Corporeal" move offers pretty cool effects. Looks like it might be a good old-skool RPG for the 360. Due out at the end of August, 2007.
Bioware's Mass Effect is also coming soon...if November, 2007 fits your definition of "soon." But hey, it's Bioware. I'll wait.
I never thought I'd say it, but I'm crazy for Hellgate London. This is nothing I usually would dream of playing, but something about it compels me. The only launch date I can find is for Summer 2007...whatever that means.
