So I wouldn't throw out the console just yet.
My guess would be that games that Nintendo was thinking about greenlighting for the Wii U for 2016 and beyond however are quietly being pulled though.
Could be. A 4 year console life (through 2016 with a final trickle of games) would be short, but something they could overcome.
They could then release a new more powerful system without any controller (or a pro controller), allowing you to use your wii motes and tablet from the old systems. And if you never bought said system, sold seperately.
