I think nintendo will want to launch the NX system at $250 which will mean fairly modest hardware otherwise they will incur hefty losses and we know this just isn't part of their philosphy. Now this will mean it is still more powerful than the wii u but just below the level of an xboxone. For me this isn't an outlandish prediction at all if anything this is a safe bet because everything in their recent past and miyamoto's recent statement all point to this being true. I just can't see them releasing another $350 home console, they got burnt with this pricepoint for the wii u and they will go back to releasing cheaper hardware.
Don't kill me this isn't clickbait but an honest prediction, i will buy the NX day one whatever the specs and zelda and metroid are my favourite franchises of all time.
