I most wanna see if the 3DS XL rumors turn out to be true.
I really like the 3DS but the more I use it the less comfortable it is. I think a lot of the problems I have with they system could be remedied by simply making a bigger model. That and having a larger 3D screen "could" mean that the 3D effect has a larger viewing angle which would be great since a lot of the games gyro-styled targeting kills the 3D effect for me.
Outside of that generally more info about the WiiU would be great, it seems that Nintendo is really reaching out to third parties this time around and I'ed like to see what they reveal this time.
