I like how the op assumes the X360 user will automatically go to X1. Trends say they'll likely migrate to PS4.
Also, wasn't FIFA an Xbox centric game as well in the UK? The difference in sales between the FIFA sku's was similar to the CoD sku's over the years. Looking at the sales of FIFA 15, Sony gained market share of the IP in the UK and PS4 ousold X1 in the UK during the month of September. (FIFA is a bigger release than Halo in UK as well)
