Right now we will have difficulty determining who is leading mainly because the system sales and margin of errors of both cosoles overlaps ... Essentially, if you say that the XBox 360 has sold 11.1 Million units +- 0.5 Million and the Wii has sold 11.8 Million units +- 0.5 Million you have to accept the possibility that Microsoft has sold 11.6 Million units and Nintendo has only sold 11.3 Million units.
Soon enough the Wii will pass the XBox 360 with the marigin of error included.
