For me (I know this is boring), I have to say GTA5. I haven't been as hyped for a game since... well, San Andreas!
I'm also eagerly awaiting E3 in the hope the next gen gets officially announced. If the next gen Xbox is out November, it's gonna be an expensive second half of the year, now I have to buy a 3DS for Pokemon X/Y in October! :(
EDIT - Just noticed the typo in the topic title! Badtimes!
