I did some research, released it this forum and will most likely make a new thread with updated information's.
Evidence points out that Nintendo is going to allow/unlock shaders on the Wii U that were detectable in Wii mode via hacks, eg currently 3rd party developers can access 320 SPU's that has 352Gflops performance while the September/October update should give full usage to 960 SPU's and 1056Gflops or 1.05Tflops of performance and maybe push Wii U's power consumption higher eg from 40 watts to 70 watts if 40 watts power consumption was w/ shaders that were all active or inactive if inactive then we can expect higher power consumption.
About Wii U's storage, it has flash based that is twice to two and a half times faster than USB 2.0 or HDD's inside Xbox 360 and PlayStation 3.
At least with Wii U you can have good old school way of playing your games, put a dvd in and play without installs.
