I'm aware they have many IPs. But I really don't think they're all comparable in terms of their sales potential.
NSMB was the biggest gun on the Wii in Japan. Even bigger than Wii Sports ultimately. Wii Fit was the third biggest gun, so we'll see if that takes off again.
But I don't know whether the notion "Wait 'til Nintendo releases its big guns" works that well, considering the tentpole of the launch is NSMB.
Well you have to understand that launch games don't immediately do big numbers due to lack of huge install base which NSMBWii had when it launched. Expect NSMBU to do very well in the long run.
Steady releases of good software = steady hardware sales. There's not going to be one big game that will set the charts on fire, but steady releases of good to great games. And you have to remember that these are all games that you can't play anywhere else.
Well so far that is exactly what is happening. Until some more games get announced i think the pessimism is warranted. The wii U release schedule is empty.
But does it make any sense to think that way?
"Hey, we stopped developing for Wii 2 years ago. Then we stuffed our thumbs in our asses and wished for the best for Wii U!"
Wii U release schedule is empty because Nintendo hasn't announced anything. Do you think there's nothing to announce? No games at work behind the curtains?
Ok, take a look at this list:

And then come and say with a serious face that all you expect is for 2013 is Pikmin 3 and Wii Fit U from Nintendo. Then we have Nintendo execs touting how they have learned their lesson from Wii and 3DS software drought meaning there should be steady amount of software releases.
It's been 2 months since Wii U launched. We are still in the launch window for crying out loud.
