I don't see why not. The Wii U is sufficiently powerful, it'll have a network (hopefully) upto par with PSN/XBLA and Rockstar would want to increase their profits by easily porting it over to the new console.
Plus its not like Rockstar has a beef with Nintendo, infact I would say they are in good terms since Rockstar released the GTA chinatown wars for the ds. This should be comparatively easier.
