So people in America don't know about the Wii U, the new advertisement doesn't help either.
Look at this old video: Date October 5th

This video was about as useful as asking a 3 year old to explain quantum physics. You can't base these things on a simple test of asking non-gamers (mostly) if they've heard of something that, for the most part, has been kept under wraps even to the gaming community up until recently. You can't expect people to know what something is before they've seen it, especially people who aren't anywhere near the loop like we are.
I've always thought that things I follow for a long time, whether it's an upcoming game/console/movie release, needs to be advertised more. You see crap things like Twilight commercials a month in advance, yet all the pro awesome stuff I like they get a week tops before the actual launch day. And you'd be lucky if even the people in the stores know wtf you're talking about half the time.
