I found this picture on the Xploder cheats site. It advertises the cheats system for the PS3. Great for the PS3, but there's something else I noticed. All of the games you can see in the image are PS3 games... apart from one. Look to the right and under where it says 'THE ONLY WAY TO CHEAT ON PS3' and you will find it says Mario Kart 7, a game only for the Nintendo 3DS. Could this be a possible leak for a cheat system for the Nintendo 3DS...?
