The Last of Us Part II sold through more than 4m copies during its first weekend. Lifetime sales expectations for the PS4 version alone?

The original sold 6.27m on PS3 alone, according to VGC. And the Remastered version on PS4 sold 6.27m.
Not sure how much better this one will do, but I'll say 9-11 million.

TLOU on PS3 sold over 7m and combined with TLOU:R total sales are over 20m.
