I wonder. Nintendo fans will buy it regardless but what about the rest of the market? How many people who bought a PS4 or XO would have bought a Wii U instead if it had full third party support? Would any of those who have yet to commit to current gen have jumped on a Wii U with all the multi-plats?
With those buying for themselves, I think nothing much would change. With parents buying for several members of a family, though, perhaps the Wii U would have been more attractive?
However, at the end of the day, with the perception of inferior online and graphical prowess, not to mention the lack of achievements/trophies and other standard amenities, I think the gain would have been relatively light.
