This bizarre image was posted by EB Games on its Facebook profile on Saturday. It slipped under my weekend radar, which is why you're only hearing about it now. The picture was accompanied by the message "All will be revealed...soon.", though its purpose is not entirely mysterious.
Mousing over the image reveals the words "EB EXPO", so my guess is the retailer will be making an announcement regarding the event in the near future. How the image itself relates? I have no idea. It looks like someone just disintegrated Spider-Man, but that's not particularly helpful.
If you'd care to take a guess, don't let me stop you!
