After 25 months on the market Gamecube - 5,700,000 WiiU - 3,082,000 Gap = 2.62m in Gamecubes favour.
There were reports of stores having ZERO Wii U's before BF even began. The places that sold them would have order a small supply. I'm sure they did sell out but when supply is so small that's not surprising.
Wii U Smash week in Japan was terrible and it's down a lot YOY. The reality is the system just isn't going to sell. My head is wrecked with all these numbers so I'm not in the mood to predict sales but it's clear the lifetime won't be very good.
