Gotta love how Sony are the only ones in the big 3 doing it while Europe is asleep......
I want to see what Xbox will bring... Probably just Kinnect software.
Nintendo will prolly be the new Wii2.
Sony Certainly with the PS (Ry)Vita and Uncharted 3.

Yeah, its not like Sony to have consideration for its loyal European fan base, that has to get up early for work.
