Can the market even take another console exactly like the PS4 and Xbox One? I guess we'll see with the Scorpio, but I feel like if you own an Xbox One then the PS4 is pretty irrelevant and Vice Versa.
I don't think anyone knows if the market is elastic enough for 3 regular consoles. Still, Nintendo doesn't need to be a regular console, just not have a higher price for less power. I think Nintendo should've taken a loss, and had it at $250, which could've made quite a bid of difference in sales.
We'll see when NPD comes out, though : )
