I think that the Wonderful 101's release date pretty much confirms that GTA5 won't be seen on WiiU, or at least not at the same time.

Did Killzone really get pushed back?

They should've pushed it forward.

Uhh... *Men in Black Neuralyzer flash*

But yeah, I meant to say forward, doh.  It got pushed forward to September 4th (EU) / 10th (US).
