Taken from SQEX's press release:

LOS ANGELES (April 21, 2020) – Following glowing reviews from critics across the globe, SQUARE ENIX® today announced that FINAL FANTASY® VII REMAKE shipments and digital sales exceeded over 3.5 million worldwide in three days following its April 10 release. The game has achieved exceptional digital sales, which are continuing to increase.
Pretty good in the current climate, let's see what the numbers are like after 1 month.

Hopefully they have realistic sales forecasts for this one and won't be disappointed like they were with Tomb Raider "only" selling 3.4 million in the first month when they forecast 6 million.
