Honestly, I think the Wii U looks just as different as the PS3 does to the PS4. I think the only way to really get confused is if you don't know how either one looks like very well. The Wii stands differently than the Wii U, the Wii U has more rounded edges, the size is different, the buttons are slightly different (in placement), and they have their logos on it.
