Seb Parker: Welcome to the all new VGChartz Gap charts. This month I'm introducing two new charts, PS2 Vs. NDS Shipments which will be quarterly, and 3DS Vs. PS Vita in Japan. The remaining charts consist of X360 Vs. Wii USA, PS3 Vs. Wii Europe, PS3 Vs. X360 Global and X360 Vs. Wii UK. Next month I will add a 3DS Vs. Vita Global chart, to coincide with its Worldwide launch this February.
As I missed December's gap charts I will add the statistics in with this months.
