Having just read the latest article during the Nintendo Direct article there was mentions of a new 3D Mario game in the making from the team that gave us the Galaxy games.
Also mentioned was a HD remake of the LOZ the Wind Waker and another Zelda mentioned as well. Also Nintendo also mentioned Mario Kart Wii U and also a Yoshi game too.
Whilst I don't own a Wii U now this could push me into getting one maybe late 2013 or sometime in 2014 because a big Mario game is always welcome after a pretty lacklustre 2012 by the plumbers standards. I mean I love my 3D Mario fix hopefully we might see some footage soon.
