Look up how Activision responded to Disney Infinity.
Activision certainly knows being a pioneer in a profitable market segment will certainly attract new competitors. Publicly, they've welcomed Disney Infinity as a means of increasing NFC gaming's appeal. They probably express the same thing with Amiibo.
By your logic, Activision would actually pull Skylanders from Wii U/3DS.
Nobody chooses not to port a game to Wii U out of spite. That's just irrational -- there's always logistical/technical/business reason for it
I predict NX launches in 2017 - not 2016
