Nintendo is getting better, I mean the Wii U launch has Zombi U, Ninja Gaiden 3, and Call Of Duty BLOPS2 (which would be the equivalent of the Wii launching with a new GTA game circa 2006, albeit non-exclusive), though the Wii launch did have "realistic Zelda".
Nintendo just needs more IPs that are exclusive to their brand that are aimed at the core gamer.
When you think "Nintendo" you're always going to think Mario/Zelda/DK/Pokemon/Miis/etc. but you can grow an audience beyond that if you invest in it. Just like with EA, when you think EA you immediately think sports games, but they've successful also have launched non-sports IP like Battlefield 3, Mass Effect, Need For Speed, and the Harry Potter games.
So Bayonetta 2 is a start for Nintendo, but can't be the end for them if they want to gain credibility with core players. Need to have another 3-4 new IP that's aimed at the core demo.
