well, It's obvious that a next-gen console like WiiU will be more powerful than current gen, but the point is that we are talking about Nintendo's improvement in graphics
there was a huge jump in graphics from Ds to 3DS, even if Vita is still superior in graphics
there will be a huge jump in graphics from Wii to WiiU as well (unlike GC to Wii), the thing is how big the jump Ps3/Xbox360 to WiiU is going to be, if It's going to be enough for gamers and 3rd parties to put their games on WiiU as well, It's gonna be good for Ninty
3DS is on the way to achieve hardcore's respect, as It's selling good enough at the time, with only 2 games worth getting, which are Star Fox and Zelda, both hardcore and a lot of hardcore games coming soon
3DS graphics are good enough, even if they do not get even close to PsV
hopefully WiiU will follow 3DS instead of Wii when it comes to 3rd parties support, graphics will certainly help
