Why would they? It's gonna sell out just fine.
Maybe at US.
Xbox have never sold out in many other countries, so Price drop could help.
On areas with Playstation dominance xbox needs to be MUCH cheaper to even have a chance.
PS4 still sometimes sells out here around xmas, and xbox consoles are always on the inventory.
As contrast even switch didnt sell out at launch here, but maybe in capital city. But ps4 did when it launched and PS5 preorders filled in 30s to 5 minutes here.
And few retailers have already said that first xbox s/x bach comes "early 2021"
So, why they need to drop Price?
Because at current price people just get PS5
Even if xsex would be 299€, majority would get PS5 here. That is how strong it is
