Edit. Checked the totals, it's more like around 18 million at the moment, so instead of 20 million, let's say 15 million?
unless something crucial occurs? Two crucial things happened:
- PS4 was not released one year late (360 had a one year and 8 million sale head start)
- The price differential change from +33% to -20% in playstation's favor. This alone will up the relative PS sales at least by 50%, and decrease the Xbox sales by 33%. I'd say do the math, but the math is up above, already done.
