This is what the extroplation says the sales should be for 360 each of the next five weeks:
884,859
1,027,383
1,433,174
1,523,541
638,378
This is what the extrapolation has for PS3 the next five weeks:
619,181
683,600
883,209
943,300
577,420
These would be the 360 over PS3 sales gap for the next five weeks:
265,677
343,783
549,965
580,241
60,958
I don't think the gaps will be quite that high but I do think they will be high enough for 360 to beat the PS3 sales in 2011. You can cut those gaps down by 44% and the 360 would still beat the PS3.
