Actually if Wii U was launching against Wii I probably would get the Wii instead.
Oh come on, do you even remember the Wii's launch lineup?

The majority of the Wii's launch lineup was crap shovelware and out of the three games Nintendo released, one was a port of a Gamecube game. The Wii U might have lots of 360/PS3 ports, but at least they're port of good games for once. Plus NSMB U and Pikmin 3 are much stronger titles then Twilight Princess and Exite Trucks were. Hell, I'd even argue that Nintendo Land looks like a much better game then the original Wii Sports did as well.
It's one thing for people to be disappointed by Nintendo's lack of game announcements but the Wii U's launch lineup is already looking to be much stronger then the Wii's was. To say other wise is just getting ridiculous unless you really love to buy terrible shovelware for some reason.
