Well after seeing the MS E3 presser I am really stoked for Halo 4. The game looked just gorgeous. The new Forza game is coming this Oct and it looks good also (not a big racing fan) so maybe it gets added to the list since Forza 4 was on it last year. BLOPS II looks like COD (I will buy it I am sure) but it is a bit too brown so far.
Off topic. Splinter Cell:Blacklist was just awesome. The stuff from the last game combined with the tech created for GR:Future Soldier is pretty sweet. Gears was hard to tell anything. Tomb Raider was sweet but her panting and grunting is still distracting no matter how you try to explain it away. Of yeah South Park looks could. They were hilarious with the whole smart glass thing.
Halo 4 looked amazing - great new Forerunner weapons.
Splinter Cell Blacklist looked like a mash-up of Ghost Recon, Splinter Cell, and Assassin's Creed
