I would also go with the Wii U, although im getting the PS4 collectors version as well I prefer the experience of playing the game on the Wii U, I'm not yet convinced the two version will be wildly different especially considering the higher cost.
On a side note I want to know if PS TV is worth it if I already own a Vita, from what I can tell the vita itself should really be capable of performing the same function, considering the psp could connect up to a television.
