As previous entries have sold around 5 million each, I'll go with:
1st week - 1.8-2 million
Lifetime - 6.5-7 million
The increase is due to the critical acclaim and PS4's current level of dominance. But it's still a violent R rated game so it won't be accessible to the larger gaming audience so I can't see it getting more than 7m.
