First off, I wouldn't be too worried about the Nintendo + Disney partnership rumor, being that they are pretty much rival companies and probably will never work that closely together. Nintendo just recently partnered up with Universal Studios as well, and Disney is a rival to Universal Studios, so this is most-likely the case of someone thinking they knew what they were talking about and really didn't.
But the console is already said to work with phones and smart devices so whats the point of emulating? Will it let you project the game onto the console's screen? I have no idea if this rumor is true or if it even matters that its true or not, The graph shown at the announcement of the NX console, showed us how the console would work with smart devices, so I have a feeling that it doesn't matter if the console can emulate android games or not, because it will most-likely work with android devices in some way or another. The game emulation would just be an additional feature.
Another rumor spreading around is concerning Amazon. apparently Nintendo was approached soon after announcing they'd be making some smart phone games, by Amazon, asking to get their new games in their app store. To me, this rumor seems more believable, but I cannot confirm anything.
Game on and Keep it Rehl!
