I don't think I can agree. I mean, I'm sure being in Latin America and being at the tail end of support for less global products skews this a bit, but ultimately these are two big global publishers selling globally.

For what it's worth, Steam is willing to sell me any currently available Steam Deck in my region with 3-5 day delivery. There currently isn't any Switch 2 stock on Amazon or the local top specialty game retailer. Checking a couple other major retailers it sure seems to be sold out everywhere for now. You'd probably have a better shot at a physical retailer.

So I'm saying that Valve has stock of the Deck and has for ages, at least in the territories it supports through direct sales. Which is expected, the thing is not new anymore, but it suggests that if it needed to ramp up production it could, it just doesn't have to.

You could argue that this is not apples to apples, and it may not be, but the difference is so large it may not matter. The Switch 1 by itself was about as large as all of Steam combined, let alone the Deck by itself. The Switch 2 did in weeks what took the Deck years to do, crucially at the same price point (the Switch 2 is cheaper than the OLED but more expensive than the LCD). Considering how much of the marketing and the community focused on the Deck being a Switch killer based on the performance advantage it had, I'm going to say they are close enough competitors and the gulf between them is large enough that whatever differences you want to account for are accounted for.

Which, again, doesn't speak to the quality of either piece of hardware, but it does to the notion that the Deck has been a runaway success or that it has overwhelmed Valve's expectations.
