I reckon it'll do well. A solid amount. It won't set charts on fire, but it'll outsell the Wii U and Gamecube and approach N64 & 3DS.
It'll do better than the WIIU but that's hardly a high bar to set. It won't sell gangbustes though
This will flop.
Just like the 3DS it will have a rough start, but will start to do better when the price come down.
Uh, hasn't the 3DS sold almost twice as much as the N64?
