Does anyone have any predictions on the availability of the OLED version?

I was not around for the OG release, but I understand that it was in high demand for a fairly long time (many months?). I’d guess that the OLED will be easier to get, as many of those interested in the deck will already have one without the need to upgrade, but who knows.

Has Valve said anything about their supply or their prognosis of sales/availability?

I live in a country that Valve does not ship to, so logistically it would be difficult for me to order it without having a general idea about when it will be shipped.
