Not bad for the first 2 weeks, but it needs to continue to sell to be actually good numbers, at this point there is a good chance it isn't all that above the recouping point.
The game cost over 45 million to be made
https://www.nrc.nl/nieuws/2017/02/2...tie-van-nederland-is-gemaakt-6962270-a1547873 , this almost certainly does not include marketing budget which as a general rule is a very good % of the development budget, public rule of thumb is marketing = dev budget.
If we assume that was true for this title (it can be less it can be more), that would put it at roughly 97 million $ as currency conversion stands today ( was stronger when this game started), so lets call it 100 million to make math easier.
If we assume all these 2.6 million copies were sold at 60$, and that Sony made a 40$ return on each copy, that is a 104 million $ revenue, or a profit of 4 million $.
Although ofc from now on it is all profit, and while console games tend to have short legs, this one being a sony exclusive should still sell a couple more million copies, so long term it should make a nice return, probably enough to pay for the sequel.
Not that it matters all that much to Sony ofc, from a business perspective the money they make from their games is chump change, it is all about growing the platform so they can take their cut from games released on their consoles, and get money from the online subscription.
It does however go to show why outside of some stupidly big titles like halo (which will probably stop being exclusive and show up on PC), publishers are not really doing AAA platform exclusives anymore (those the division sales jesus christ).
