I think with the pro release and some Xbox owner migration they may top last year's "best ever sell through" stats.Microsoft has given up with Xbox, the lack of significant deals during the holiday season means that they truly don't care anymore.
But PS5 is not really competing with Xbox at this point, it is competing with itself.
The question is if with these deals and the launch of the Pro, Sony can avoid a sales decline compared to last year during the holiday season.
This will determine if in January they will keep their 18m forecast or if it will be revised down.
