Nintendo haven't been putting out the software to get me interested in it. Honestly, Pikmin 3 is the biggest factor making me want a WiiU right now, but on its own that's really not much of a sway.
I did want LEGO City Undercover, but I've kinda gone off the idea after having played a few other recent LEGO games (they're alright, but not something I'd consider worth buying a console for; more like something I'd pick up in a bargain bin for £8 and get a few days of enjoyment out of).
And third parties aren't doing anything on the machine. I'm not even talking about multi-plats - they're there, but I can buy them all already on PS3 (or will be able to on PS4 when I get that). I'm talking about the nicher stuff that made the Wii interesting. Little King's Story. Fragile Dreams. Muramasa. Throw in a few exclusive spinoffs of series I love (i.e. SSX Blur; FF Crystal Chronicles) and then we'd be talking.
WiiU has none of this already and none of it on the horizon. X may be the second thing I want to play on WiiU, but that's still only 2 games. I'd probably pick up Mario Kart if I bought the console, but it's not swaying me towards it particularly.
Nintendo would have to dig out some of their other IP's (Star Fox/F-Zero/Battalion Wars) or, even better, make something unique and new and exciting targeted at me and then I'd be more likely to jump on board. Or 3rd parties (particularly Japanese ones), could fill in the gaps with a library of JRPG's and weird, niche, interesting stuff.
(Conversely, they've done pretty much everything right with doing this on 3DS and that's why it's going to be the next console that I buy)
So no. It's nothing to do with power.
