Keep up with January I'll give you advice on what to put for the future:
March: Fight Night Round 1, Yoostar 2 (Uses Kinect only), MLB 2k11, Dragon Age 2, Homefront, Top Spin 4, Crysis 2, Lego Star Wars, Nascar, Shift 2 (Huge Month)
April (Tentaitvely) - Carnival Games: Monkey See Monkey Do (360 Kinect exclusive!) Divinity 2 Dragon Knight Saga (Console exclusive!), Michael Jackson: The Experience (Kinect use exclusive), Mortal Kombat, Portal 2
May - Duke Nukem Forever, LA Noire, Brink, FEAR 3, Dungeon Siege III
September - Gears of War 3
October - Ghost Recon Future Soldier (or so Gamestop claims), Silent Hill Downpour, Batman Arkham City
November - 11/1/11 Elder Scrolls: Skyrim
Everything else doesn't seem to have a set date, and we will be waiting for all the E3 surprises to fill the second half of the year!
It's just that simple.
