Just because the hardware is capable of 1080p, doesn't mean it has the power to do it for every game. Nintendo wanted HD (720p) at a high framerate (60 FPS). They knew they could still do some great graphics and meet that. Going to 1080p they would have had to make cuts somewhere.let's stop that considering the hardware crap. Shin'en already stated Wii U can do more than major developers are stating. Is pushing this game to 1080pworth the extra development cost to Nintendo?
That's the question when I was saying they could I meant the hardware is capable but to them the jump from 720p to 1080p wasn't worth the visual upgrade. Just like Shin'en said they had nano assault neo at 1080p but they dropped it to 720p and used the extra power for graphical effects.
Wii U has plenty of oomph to make beautiful games, but do not spit out "it's just development costs stopping it from being 1080p."
And as a note, I am so g-damn excited for this game now. Very happy Wii U owner right now.
