My prediction of tlou 2 selling over 5 million week one will be true5 million is ridiculously huge, only two PS exclusives have ever got over 3m and Spidey holds the current record with 3.3m. 5m would be a 50% jump over that record, which was set by one of the most iconic IPs in modern pop culture.
Breaking the record in any way would be fantastic, the first game sold 1.4m first week so that would be way over double if it pulled it off. Personally I think it'll manage an incredible 3.5-4.0m, anything over that would be insanity. I suppose a 94+ meta revealed a week early could give it a big push like with God of War.
