The very same wii u that devs strggled with to get games running well?
As its been said before its crucial to actually build an audience to be receptive to games other than just Nintendo. EA wouldn't even be at the table if it wasnt worth pursuing
Depends on the game. PS3 had similar problems too. Heck, Mass Effect ran worse on PS3 than any other versions.
"Nintendo games" means nothing. Fire Emblem, Xenoblade, Super Mario 3D World are all Nintendo games. What do they have in common ? Nothing.
It's nonsense to get the same thinking we had before Wii U aka "It needs COD, FIFA, Madden, GTA to sell". No, it doesnt. Nintendo could fit the bill to have all these games day and date on their next console, they'd sell a lot worse and it wouldnt sell the console. People nowadays choose an ecosystem.
And what Nintendo needs is a solid and unique ecosystem, with a steady release of great games, not like the joke that was Wii U's first party output for most part.
There's a reason why 3DS is nearly sitting close to 60M units sold despite all its shortcomings.
