That's true, they've gotten better. And even the gamestop ceo knows it. It's in another Forbes article talking about how he's certain the wii u will make a comeback.
But that's cuz mario kart 8 alone skyrocketed sales. Still a very lonesome game atm.
And then he knows the hype that Smash is making, and he specifically mention the amiibos- which we've already agreed is that the amiibo will be such a huge moneymaking cash cow farm. *nods to skylanders and disney infinity*
And then yeah, Hyrule warriors and a few other games.
Still not many, but enough that nintendo will start making up for lost ground. It still won't be enough lure back many third party developers. There will still be a shitton of games that will port their games to every console BUT the wii u. Nintendo will have to do the vast majority of the work with its own IP's to make it a real success.
