Seems the GTA to Wii transition will never rest as a new story reporting that such things are happening has emerged again. This time it has pictures to go along with it if that's any more convincing for folks.
Anyways, people left comments on that article saying it looks like PS3/360 visuals with Wii controls, but its hard to judge how sharp they may be. In one shoot it looks like Wii visuals as a tree in the background looks a little off.
It was bound to stumble up again, and its coming to DS why not Wii? Maybe this will be a key piece of E3 09 although if its even true simply tacking on Wii controls to what looks like GTAIV shouldn't take too long.
