It will be a decent enough port, It wont stand up in a straight comparison to the PC, One, and PS4 versions of course.
The sales on all consoles will be low, i think they should have stuck with either PC exclusivity or PC & WiiU.
WiiU doesnt have any racing sim games, but PS4 and One have a few so its going in to an already competitive market on those consoles. It could have found a strong niche on WiiU
