All it needs is a gameplay trailer for all the games that are coming out and the sales will skyrocket.

And remember, not everyone buys a system the same time their favorite game comes out.
show them a hint that it will come out and they will buy the Wii U.

Who told you that? People usually need more than a video to want to buy a system.
