What is the case for the Wii U getting PS4 and next Microsoft console content?

Isn't this happening already? Didn't the developer of the Witness say the game won't be on PS3/360 and Wii U due to low specs? It's definitely coming out on PS4 and I think it is safe to say it will come on Xbox next and PC since it's not a PS4 exclusive.
