Games Radar has uploaded a video showing the Wii U version of Sonic & All-Stars Racing Transformed. The video keeps up with the tradition that 90% of all people playing Sonic demos on camera suck. The course shown in the video is a new Seaside Hill track, a location which already had three courses in Sonic & SEGA All-Stars Racing.
The player notes some issues with the version like that looking at the screen on the Wii U Gamepad is distracting and more importantly, that the framerate has trouble keeping up it at 30fps. Of course this is a work-in-progress build, so this will probably be fixed in the final version. (hopefully) The Wii U version will be available on the launch of the Wii U, which is November 18th in the US and November 30th in Europe.
