If it wasnt supply constrained and they sold say 1.5m retail I'd have guessed a natural 20% digital attach ratio for this. That is 300k digital. So i guess all things considered ~2m isn't beyond the realm of possibility it's just mind blowing and hard for me to accept..
I think a big issue is that most people use MC physical with Famitsu digital numbers. so 1.25m physical (2 days tracked) and 750k digital is 38%, which is higher than the global average by a lot at 30%.
But recent posts say that it is shipped (transit) plus digital which I can believe more. And the report in the op is 3 days tracked vs the 2 days in MC, unless I'm mistaken.
