Out of curiosity. People seem to be attacking the OP for his username and avatar. Do you by any chance do the same every time you enter a thread and someone makes a point about Ninty and has a Ninty avatar/signature/username? Please be honest.
As for the OP's prediction, I think that Wiiu will beat vita eventually because I feel like Sony is about to drop the vita (though hopefully I'm wrong about that).
As I said in another thread, I find it meaningless unless one of the two beats the other by a large margin. Because good hardware sales usually translate to decent support by 3rd parties (in Sony's case 1st party too), and neither one is getting significant support from western 3rd parties.
