WiiU games cant look outdated compared to Ps4 Xone games.
They have similar if not identical shader capabilites etc. The resolution will be cut in half and the framerate will not be 60 but 30fps or whatever and then you have the same game just needing 1/4 of the power.
Wii looked outdated because it was basically PS2 era
Wii lacked most of the stuff PS360 were able to handle. And third party developers could not be bothered to implement "replacement effects" that they used in the Gamecube era etc (Splinter Cell on GC has better lighting than 99% of third party games on Wii) because the newer engines simply could not handle "old school"effects because noone implemented the compatibility yet or they were removed (why have messy 2001 oldschool code noone needs in a 2010 etc engine?)
So they removed the effects completely instead of trying to mimic PS360 visuals with older effects.
WiiU on the other hand wont have that problem because the capabilities are very similar to PS4 and Xone.
I mean when you look at Resident Evil Revelations on 3DS or Mario 3D Land they dont really look outdated compared to PS360. Sure they look inferior but def not outdated. PSP looks outdated because it also lacks all the shaders etc.
BTW I would even say PS360 wont look outdated compared to PS4 and Xone when developers replace effects those two cant handle with PS360 era effects.
I mean the PS2 era had almost NOTHING. The only thing the era had was crappy shadows and very bad lighting. PS360 with their überlong shelf time made devlopers come up with 99% of real world effects to make their new game look better than their old one. We gave good shadows, great lighting, tons of particle effects, reflections, refractions, self shadowing, bokeh etc.....
There is not much left other than refining those effects and SCALE of worlds.
