I'll definitely go with 10 million. The game is still selling on PS3, and I can see it inching ahead another million or two. On PS4 it'll definitely be a system seller. Normally I'd say remasters/remakes don't move systems, but I've seen so many comments lamenting the fact they went with 360 because of this game. With TLOU on PS4, they'll likely jump on that in order to not make the same mistake twice. I can definitely see it doing 2-3 million on PS4, which would put it's total over 10 million and every bit deserved.

the PS4 is already at 6 million. VGC is massivly undertracking it.

OP: 8.3 million. 

Quote trees guys. Cut them down.

kowenicki is right. That 6 Million number is shipped and digital. There is no real way to know just how many are on store shelves or what the digital:retail ratio is.

I would say 6-7 million on PS3 and another 2-3 million on PS4. So 8-10 million means I vote middle with 9 million.

12 million on PS3+PS4.

im sure there is 1.5 million copies sitting on store shelfs one year after release. makes sense. 

With 6m shipped, 6m sold is going to happen. 

Indeed. Nobody said otherwise.

Around 8 or 9 easy
