''Of course there are still a ton of variables here, for example the development of the mobile/tablet market might eat into the PS4s sales, maybe the Steam Box and of course the X1, maybe Amazon or Apple decide to enter in the race, maybe the Ouya (ok, maybe not :D).''
Taking this into consideration, there is no way the PS4 can do better than PS2. Also don't forget that it tooks 12 years for the PS2 to reach 155M. Considering the WiiU+3DS will sell at least 130M, I don't see how the PS4 could outsell them.
