I dunno if too many people are going to buy consoles for Infamous DLC but you're right that this Software stuff extends into the early 2015s as well. Shit guys, Bloodbornes a comin'.Add Infamous First Light, LBP3 and Driveclub in between those things and the fact that 2015 starts with Arkham Knight, The Order, The Witcher 3, Bloodborne and there it no room for Xbox to react in a long while.
The question now is if the PS4 will be able to get anywhere close to PS2 levels of sales, otherwise we are going to see a sizable shrink in the market compared to 2 generation ago.
15m seems way low if it is at 9m+ already.
