5 million is almost certain in week 1, so saying 5 million in whole of Q4 is just strange.
Re OP about movies: It all depends on your definition of week 1. If Pachter is talking the first 7 days, then I think one or 2 movies have done as good or better in their first 7 days on simultaneous worldwide release. If you are talking about from release until the end of the first weekend then you are right, no movie has ever done $500 million in that timeframe. in fact none have done $400 million in that timeframe.
$500 million at an average worldwide sale price of $70 USD (is that a reasonable price average?) = 7.14 million copies sold. That's A LOT of game!!
