If Brawl did 2.7mil(in 12 days), is there a chance Smash Ultimate beats Halo? Also Halo is for 12 days not 3 and Halo is disproportionately bigger in the US and UK than anywhere else. Like Japan for ultimate was great, but The US is so much bigger for smash and Europe for switch has been toe to toe with Japan on many titles so imagine 2.4mil just from Europe and Japan. US should be huge. That means Smash has a chance of having the biggest first-week sales of  any exclusive. It's weird that there is no press release but maybe they want to hit super hard like this many million in the first week and how much switch sold with it. So stay quite and hit with a bigger bang than anyone expects. That would be something

4-4.5M first 3 days
