Even Sony tried to hide their date in the early days of the PS3 era, it's 100% a loser tactic which is why MS has adopted it for the last two gens.This is the same company in the Xbox 360 days that was eager to give data on how many consoles they sold to anyone who would listen. Even now they still know that data but they don't publicize it.
Just like gameass is a we're last but we're rich loss leader tactic, if Xbox1 had the sales of the PS4 or Switch gameass would be nothing like it is today.
