This is not the first time that the big N has tried sticking a screen on a controller. I remember when the Gamecube came out they made a cable for the Game Boy Advance that connected it to the Gamecube. It was supposed to allow the Game Boy to act as a controller for the Gamecube, downloaded mimi games onto it (much like the Dreacast controller could except not store them to memory), or be used to display information and the such from the game your playing. Though I only ever saw this used once with Phantasy Star Online.
So to me this new controller seems like the next incarnation of this idea. Essentially taking what they have learnt from the DS and the uDraw thing. Slapping them together and making this new contraption.
The console it's self....
Well I will wait to see what comes from the hardware before I make any kind of in-depth comment about it. Other than it looks like a redesigned, beefier version of the Wii at the moment.
Is it enough to tempt me back to a nintendo console?
No it's not. I gave up with the Wii and Nintendo a while back and I can't be bothered with it.
Is it enough to put Nintendo back in the Game?
Well with the kind of marketing and brand recognition that Nintendo have then definitely. If the pricing is right and it's accessible to people then it will be eaten up just like the Wii did on launch.
I am not sure if they should stray away from the casual scene as much as they want though. Seems like thats brining in money still.
