Is the Xbox Series X completely sold out?

I wanted to buy an Xbox Series X tomorrow, but I read that everything is sold out.

Isn't there even a chance that Media Markt / Saturn has consoles for non-pre-orderers?
I once thought that it was not allowed to sell a whole lot of a product online before it was published? So that at least a few pieces have to be sold in the shop

A few should be available online at release and maybe even in stores in major cities, but the chance of getting one is very slim. There will definitely be some somewhere.

At 9 o'clock today you can order again

Online or in store?
