The official site just updated with the news. Looks like it'll be in their next financial report. Not counting different SKUs. This puts it as the 6th best selling RE title
Resident EVil 5 - 9.5 million
Resident Evil 6 - 8 million
Resident Evil 4 - 5.9 million
Resident Evil/Resident Evilirector's Cut - 5.08 million
Resident Evil 2 - 4.96 million
Resident Evil 7 - 4+ million
So the game has finally made it's expectations. Even if it was a bit behind in terms of expected dates. It'll be interesting to see if it can reach the 5 million by next year that they expect with the Gold Edition.
Looks like the legs on Consoles have been far better than those on PC. Congrats to Capcom.
