E3 is full of suprises, and one of them may very well come from Bethesda if a placeholder listing by Amazon UK is any indication.
The online retailer currently lists "Bethesda E3 2014 Dummy" for Xbox One, PS4, Xbox 360, PS3, PC, Wii, 3DS, and Vita with a tentative release for sometime in 2014.
The placeholder suggests that Bethesda could be planning to unveil a new title during E3 next month, but doesn't necessarily offer any clues as to what it could be. Given that the just-released Wolfenstein: The New Order includes access to beta for the new Doom game, I'm guessing that's what it'll be. I highly doubt that whatever it is will be available on all of those platforms though.
