What do you think it will sell...

A) Global First Week sales

B) Lifetime

Can it pass 3 million?

Dunno.
But it will be the biggest selling game in the franchise

OP was tl;dr.


OT - ps4s.

That is truly difficult to say. On the one hand; there aren't really a lot of good titles to compete for gamers' attention on the PS4 right now but on the other hand; it is a tad foolish to assume that every single PS3 owner who owned and enjoyed the two first ones would suddenly make the 8th gen jump due to this one title, it's a big investment and it is equally unlikely that a game with a fairly peculiar premise will draw in vast amounts of new fans as well.

It's a complete joker from where I'm sitting, could range from 1 million to 3.5 million but I find both equally unlikely and will settle somewhere near the middle for the sake of sheer balance on my own part. I'll guess somewhere between 1.75-2.5 million (I'm leaning more towards slightly shy of 2 million though, we also have to consider that, traditionally, this is not a hugely favorable time of year for game releases), should be possible since there are already five million sellers on the platform and four of them are multiplatform, a good quality exclusive should do quite well.

I expect it to get to +4 million LTD.

it will sell pancakes

Will be the best-selling game in the franchise. More than 3 millions seems doable.

Infamous Second Son will probably end with 3 million or so. It is a very hyped game and it is also the first very big PS4 game since the PS4 launch so it will probably start with nice numbers in all major regions ( I will be pretty shocked if global first week numbers are going to be lower than 500k), but  I think that its legs aren't going to be that good and it will stop selling like crazy in 2015 or so.

600k fw, 3.3m lifetime

FW: 550k

LT: 2.5m lifetime.

And to anwser OP's question: I do not believe it will pass 3M.
