Nintendo has had A LOT of of time for making F#)(/$ Pikmin 3, I hope it's a launch title or at least for early 2013.
Maybe we will get casual first party games, Wii Sports U, Wii Play U (o_o).
But the best of this is that third parties are finally making decent games, so we can expect better launch titles.
I'm guessing the Wii U will come with a Wii Play type game showing off what the console can do. The last couple consoles they've released have come with some sort of software to show off the systems strengths.
