Ghost of Tsushima sold through 2.4m in its first three days. Lifetime sales expectations (PS4 only)?

Well I think I said at one point that it had a shot at 10 mil, so now I'm comitting to it.
I can only see that happening if it doesn't get a PS5 re-release though, but I'm starting to think Sony won't do as many of those this time around.
