Well its obviously Shenmue 3 but seeing how were not to sure about its development. Where is Fable? Im more anticipated for this game at the moment but once I get it, it will switch to Halo 2. And if shenmue 3 not out till then it will turn to Shenmue 3.
I'm most looking forward to Sonic Heroes. Either that or Starcraft 2/Ghost. Or Soul Calibur 2 (I know it's out, but I haven't played it yet on console).
