Dont think XSX has production to even hit 14m by end of 2021.
PS5 for sure. It is half way there, will be a walk in the park. Xbox won`t likely cross it before March 2022.
And this time around we can`t fault "reveal fiasco". MS production is in line with their sales expectations, so they were nowhere near as optimistic about the sales number as xbox fans on the site.
They were not optimistic but they also miscalculated the demand ratio of X vs S. They though the S was going to be way more popular but now they should have a better idea and they have time to adjust production before the holidays.
