Quote from Darkjak's original post:
Pachter said that for the Wii to succeed, the console will need games: both the biggest and best multiplatform titles, which the Wii lacked, and killer apps, which to be honest the Wii never had either.
Did you know how much the 'Just Dance' series (before it went multiplatform) sold on the Wii?
"Ubisoft said in a statement that the currently Wii exclusive franchise has sold 14 million units to date worldwide." (Jul 2011)
The reason I'm quoting Just Dance is that I think it's difficult to predict what games people are going to buy. Nintendo changed things a lot with the Wii and widened the range of people who would play video games. However I don't see a massive game change with the WiiU. All I see is more of Nintendo doing the same thing but with their current IP's running on a higher spec console.
Above all I want games to be good and fun to play, I don't care what system they're on.
