Holy ****, there it is. 4.4 million in the first weekend PHYSICALLY. not as much as RDR2 though, which had 4.9 million in the first weekend, but still, this is the fastest selling game of 2018 by console, as PS4's games sold about 3 million each in the first 3 days.
Eh initial shipment for RDR2 was 17m. And it sold 4.6m retail week 1 on ps4 which is higher then Smash. With digital it would be even further ahead.
