I got it for my birthday 2 days ago, I'm playing through the Russian campaign right now. I'm in the battle of Stalingrad, I think I'm nearing the end of that. It really is a lot of fun, and a big graphical improvement over the original Xbox. I don't have LIVE migrated yet, but I played multiplayer with one of my friends and it seemded like it would be amazing. We didn't have much fun with the multi-player because the maps were too big for just 2 people, but with 3 or 4 more it would have been incredible.
All in all, I'm very impressed.
