There are three third parties that support damn near anything, where bragging about their support is like bragging about having a nose, and they are Activision, EA and Ubisoft. The silliest arguments about the Wii U attracting good third party support prior to launch always revolved around games from these three companies.
Well Nintendo has now pissed off all three. They effectively have nothing now. What is the Wii U's future release schedule going to be? Five retail games a year, all made by Nintendo? Retailers don't carry videogame systems that have no games. That's a situation where not counting eShop really makes sense. Gamestop, Best Buy, Toys 'R' Us, they don't get a dime from the eShop. Unless Nintendo expects to sell Wii U hardware exclusively online they kind of need to keep physical retailers happy to get the console into people's homes.
I just don't see how this situation with third party support being virtually non-existent and Nintendo being incapable of making games faster is going to last for any amount of time, especially long enough to be the typical timeframe of a console generation. This isn't going to last five years.
