The article brought this up, but I'd say this says a lot more about the WiiU than it does the game itself. You could have the greatest game in the world, but if only 5 people (that's an exaggeration, people...look it up) own the console your game is on, it's not going to turn a profit.
I really feel bad for the Nintendo. Through the early years of the prehistoric console wars, I was Nintendo all the way. NES was the place to be, then the SNES kicked the Genesis' ass, and I preferred my 64 over the Playstation. Never had a Gamecube but my brother did and I enjoyed a lot of the games for it, then I got a PS2 and eventually a 360 because all my friends were playing on a 360. Nintendo never did anything to me to lose me as a customer, I just kinda...lost interest in them. Sadly every time I thought about picking up a Wii even if it was only for a select few of those ever-resurrected franchises, the store would be sold out of them.
I honestly do hope things turn around for them. For full disclosure, however, I do have to admit that I have no intention of getting a WiiU. u.u
