the source linked even has clickbait in the title.. but hell i'll bite.
1) wouldnt bother to mention NDA if he was going to leak information anyway.
Capcom and EA do not have devkits, I can tell you that for certain, if theyre still developing the OS for the system to run on they wouldnt waste time providing third parties with devkits that dont respresent the final OS/architecture.
How is sonic in development if Sega, Dimps or Sonic team dont have devkits?

Getting tired of these fan-dream lists/rumors for NX, just wait till Nintendo actually announce something solid and you have less of a chance of being dissapointed if the wet-dream lists some random guy made up for hits dont magically hit the mark.
