Uh, yes? I googled "vive 2.0 base station" and they're just selling them on their website. I ordered one and got it shipped to my house a couple of months ago.
They come in a Vive-branded box, but the base stations themselves literally say "Valve Index" on the back. They're identical to the Index ones, and can be matched/used with Index ones too.

Dunno if they do this outside of the EU too.
