Lame looking kids game, white DVD case, Wii logo in the corner. Looks like a typical Wii game. If you mixed Wii U games with that kind of cover with Wii games on a shelf it would take effort for me to spot the Wii U games. I could spot the difference between PS1, 2 and 3 games from across the room.
CNN thought the Wii U was a peripheral for the Wii and Nintendo was demoing the real system to them. With THAT case and the current system design, no one but the most hardcore is going to know this is a new system... unless Nintendo really hits everyone over the head with "this is a new system, not a Wii accessory" in their ads. I hope for their sake that this is just some mock-up done by a store or web site unaffiliated with Nintendo.
