What did people expect when its called excitebots? Fact is Nintendo make great games for all audiences, they are experienced at making kids games better than anyone else, they didn't sell many of the original.
Frankly i think its safe to assume that waiting for more info is a good thing but knowing its a MK clone isn't the worst news in the world, especially from Nintendo.
Another thing because its a quite release it might be like Disaster, too embarressing to publicly associate with the company, and if thats the case i will be pissed.
“When we make some new announcement and if there is no positive initial reaction from the market, I try to think of it as a good sign because that can be interpreted as people reacting to something groundbreaking. ...if the employees were always minding themselves to do whatever the market is requiring at any moment, and if they were always focusing on something we can sell right now for the short term, it would be very limiting. We are trying to think outside the box.” - Satoru Iwata - This is why corporate multinationals will never truly understand, or risk doing, what Nintendo does.
