Necrolipe is not reliable, he sometimes knows things, and sometimes he doesn't but will pretend he does. His info seems to be mostly from marketing material, so I think he only gets access to stuff that are very close to happening, like trailers and ads after a direct. Personally, I think the possibility of him fully knowing Square's and Sega's future lineup is farfetched, to say the least.
Nate has also shown to be unreliable in regards to the next Nintendo hardware.
I don't see a reason we should trust the word of any of these three people over the other.
