Nintendo's in a tough spot right now, and I figure this would be a great place for us, their biggest and most loyal fans, to come up with some ideas for how they weather this storm.
My first idea is that Nintendo should use their sizable war chest to purchase Sony and Microsoft's gaming divisions out from them so that they would by default have the best selling console on the NPDs.
Another way they could go about it would be to call in Yamauchi's old favors from the Japanese mob to force their competitors out of the business through threats and intimidation, while simultaneously blackmailing third parties into throwing their full support behind the Wii U.
My final idea would be for Nintendo to change the name of the Wii U to the Wii You as a means of trying to trick some of their loyal but less-attentive fans into buying the same thing over again.
