Ninty hasn't created any new I.P's they can use in future generations, why

[woopah]

nintendo's stratergy was to get out the big francshises first in order to spur sales and give third partys a solid userbase. as time goes by we will see them make new IPs

so far announced/released i can think of endless ocean, disaster, spawn smasher, line atack heroes, dynamic slash, monada and cosmic walker. plus this doesnt take into account all the franchise revivals, like sin and punishment, punchout and pilotwings (im sure its coming)
