This game looks like it will be outstanding! I just got a 360 for Fathers Day and I'm blown-away by how good this console is. XBox Live is great! The graphics of games like Kameo, Oblivion, Ghost Recon (GRAW) are amazing. I have all major consoles and this one is truly next-gen. Sony is in trouble.
It sounds like they are on the right track with this RTS. Most of the interviews I've seen are about how they are thinking about the controls for an RTS on a console. This is not just a port of the PC game and that's huge.
July 7 is official retail date I believe.
