If DayZ were to be released for Xbox, I'd give that a go. I didn't like the feel of the PC version, and if they patch it up for 360 I think it would be worth a shot. If Fallout 4 is ever released...
The Elder Scrolls: Online sounds promising as well.
Whats up wth you people and GTA 5???
Anyway, I am expecting
Sly 4, Kingdom Hearts 1.5 remake HD, Final Fantasy 13: Lightning Returns, FF versus 13, FF 14, Pokemon X and Y, Shin Megami Tensei: Soul Hackers
