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.

Killzone Mercenary's release date got moved back a week because it clashed with GTA 5.

Using OP's logic, this is a sign we may be getting GTA 5 on Vita?

Excellent news!

Ohmagosh, your avatar is so cute that it burns.  *-*

Honestly, though, I'd rather have The Wonderful 101 on the Vita than GTA 5.  Seems so perfect the the Vita's touchscreen.  Stupid Platinum.
