I have two problems with what's being said in this thread.
One, while I can't speak for Europe the Wii U IS in fact being advertised. Every single first party Wii U game has been advertised on TV on stations like Nick, Disney, and Cartoon Network. Latest being Kirby followed by Mario Party 10.
Two, there's this stigma about the Vita's library lacking in quality when that's far from the truth. Most people probably just look at review scores where Vita games are criminally under scored because they weren't made for consoles, instead of actually playing the games themselves.
Games like Killzone Mercenary, Gravity Rush, Tearaway, Uncharted Golden Abyss, Persona 4 Golden, LittleBigPlanet Vita, Freedom Wars, DanganRonpa, Ys: Memories of Celceta Wipeout 2048, Unit 13, and Soul Sacrifice Delta are all great quality games that I would say are just as good if not better than most games on Wii U. And that's not even getting to the "anime Japanese" games where some of them also happen to be great games.
