Jeez you are slow when it comes to Xbox reality.
Series X has been readily available across Europe and even the UK for months. Its supply increases in the US when they started doing the Forza bundle, I would imagine it's gotten better since.
You just refuse to accept that it's not a supply problem; it's a demand problem. Whether the S or X, demand for Xbox hardware is dwindling. That's something Microsoft have to resolve but pretending like Series X is a unicorn to find for purchase is not going to do any favors.
