Lets do a fact check - which is quite easy as there are not so many cross platform titles out there.
Skylanders and Disney Infinity are the biggest ones which are available on Wii U, XOne and PS4.
Everybody here can lookup the sales database and do the math.
Taking the last generation into account too the picture gets even more clear: its the Nintendo consoles which have the highest attach rates.
It hurts Skylanders big to not be able to release on the Wii anymore. As it has "grown up" on the Wii.
But it is simply astonishing how many they sell on the Wii U given the much smaller hardware base.
This tells something: any Third offering a unique experience appealing to Nintendos customer base can be successful.
They just have to tailor the experience instead of "just porting".
It speaks for itself that most developers either can't do that or have doubts in their ability to do that.
