I find they probably hurt themselves having NSMB U and New Super Luigi U in the same video, but other then that I'd say it is exactly the sort of stuff gamers need to see in order to increase the Wii U's profile.
Damn shame it looks like whoever is running the show in Europe with what presume is more limited in its resources seems to have a better grasp of these types of things then the folk calling the shots in North America.
