The reason I've picked up Wii in the first place was to play Rogue Squadron, Resident Evil 0 and Remake of RE 1, Ethernal Darkness and to play fps games with motion controls. I didn't care about any of the big time Nintendo franchises and today I only care about Mario Kart, Metroid and Zelda. In other words - absolutely yes. Nintendo needs more T and M rated exclusive games.
Wii U is a GCN 2 - I called it months before the release!
My Vita to-buy list: The Walking Dead, Persona 4 Golden, Need for Speed: Most Wanted, TearAway, Ys: Memories of Celceta, Muramasa: The Demon Blade, History: Legends of War, FIFA 13, Final Fantasy HD X, X-2, Worms Revolution Extreme, The Amazing Spiderman, Batman: Arkham Origins Blackgate - too many no-gaemz :/
My consoles: PS2 Slim, PS3 Slim 320 GB, PSV 32 GB, Wii, DSi.
