The wii u yes, 360/PS3 no decision is a wierd one. It is unlikely to sell well on wii u and the 360 and PS3 could probably achieve a superior version to wii u. I know racing games are more about pushing graphics than cpu requirements normally (hence why the ps2 can delivery 1080i visuals in gran turismo) but as with Watchdogs the wii u lack of hard drive creates huge streaming data issues which the ps3 and 360 don't have. Not forgetting both ps3 and 360 have analogue triggers where as the wii u doesn't which is quite important in driving games.
I'm not expecting the wii u to achieve anything that probably hasn't already been achieved on 360 and PS3 in games like Gran Turismo and Forza. The wii u version will likely be heavily compromised.
Both the ps3 and 360 have far superior cpu resources to wii u.
Slightly Mad should use the graphic assets created for the wii u version for later 360 and PS3 versions. It's madness not to support those consoles if you are going to support the wii u. I suspect they may not want to compete with the big Gran Turismo and Forza franchises but I can imagine fans of both series appreciating what Project Cars has to offer.
