Interesting - Considering that Nintendo has partnered with a mobile gaming company a while back to make games for mobile. I personally think this is legit.
It is also powered by Nvidia Mobile Technology - http://www.eurogamer.net/articles/digitalfoundry-2016-nintendo-nx-mobile-games-machine-powered-by-nvidia-tegra
I disagree allot of big companies (EA, Ubisoft, 2k, etc.) are interested in the NX and Nintendo because of this move. Nintendo also really opened up their Developer Program. No upfront cost to join the dev hardware still costs money but it is allot less than Xbox or Sony from what I have heard.
