Well, even if the WiiU isn't selling what they wanted, it still making more per console than the PS4, and probably the XBox One. So it's got that going for it.
So what do you think Nintendo should do? I say, make a tablet free WiiU for a lower cost, bundle it will some good game, and make it so you can use your own Surface/ipad tablet with many of the WiiU pad games. Not all the games use the tablet.
With a tablet free WiiU they could seriously undercut the other consoles in price.
