First off, I need to get this out of the way...
HOLY FUCKING SHIT OH MY GOOOOOOOOOOOD HOW FUCKING AWESOME IS THAT THING!? JESUS CHRIST THAT'S EPIC AND I MUST HAVE IT!!!
Ahem... now that that's over with, I can be more measured and balanced here.
First of all, the name is tragic. I get annoyed with people bitching over something like a console's name, but to have what Nintendo hopefully see as a way to really get into hardcore gaming crowds again, having it a bright white plastic thing called a "Wii-U" is just... unfortunate, at best. I can just imagine going into the game shop now. "Yeah, can I get a copy of Darksiders 2? On the... on the Wii-U... yeah, just be discreet about it."
But name aside, let's get down to it.
It looks amazing. A lot of what they showed off in the introduction video seems kind of gimmicky. Particularly the golf thing... that's kinda a one-use "for a bit of a laugh" functionality. But there's a lot of good stuff there. The full HD visuals on the touch screen while the TV is on something else is awesome, and the integration of that screen into full-on gameplay could be really good depending on how restrained 3rd party developers are with it.
My hope is that they really do get the support for this thing. If they end up with sub-par 3rd party support and just fall back on their casual gimmicky games like they did with the Wii, it'll be a major blow to Nintendo that I really don't think they can afford to take right now.
I hope so much that this thing takes off because I really want one, but if it flops then the hardcore crowd's faith will be really shaken and Nintendo will risk losing what hardcore crowds they got back with the promise of this thing.
But with Arkham City ported, Darksiders 2, Ninja Gaiden and others that I can't remember, it has a lot of potential for them right now and they need to keep announcing more support to keep people hyping up for the release of this thing.
