Sony: Majority of 140 PS4 games are 'back end of 2014'

[Slimebeast]

For comparison I wander how many games the PS3 had from holiday 2006 to end of 2007.

To me 140 games until end of 2014 sounds plenty enuff.

But there has also been a 500-something number been thrown around. Refering to the number developes supporting PS4, or what was it?
