Yep dunno why they made it exclusively for the Wii U. There's two platforms that you just don't touch right now as a 3rd party... Wii U and Vita.
nice try but they actually were happy with AC Liberations sales and are bringing more games to the platfrom and no proof of any publisher saying their games are not selling on vita. on the contrary there are many instances publishers are happy with their game's performance on vita. install base is low but that install base actively buys games!
