Another troll thread or just another uninformed thread opener ...
Anyway: It is widely known that Nintendo changed the specifications during Wii U development. This is why the first dev kits only had 768MB RAM and later ones had 1 GB RAM for games. This had been in discussion already at the first month of 2012 ...
You really should do some little investigation before opening a thread.
The other things you wrote, about Nintendo hiding graphics api is purely nonsense.
