Is the Xbox Series X sold out yet?

Is it already sold out or why is it not available?

Yes, at the moment it can only be picked up in the markets for pre-orderers.

Today I had read something somewhere that should be available in retail in about two to three weeks.

But I don't take any responsibility for it!

If it is not currently available anywhere it will probably be sold out.

The only thing that helps is to constantly secure various online retailers and to track items for availability.

Every now and then batches come onto the market, but only online and these are quickly gone.
