This guy will have to wait for his younger brother.
It was available to buy starting noon local time. I refreshed the page until the buy option became available, but kept getting an error when submitting payment. Waited about half an hour and now it’s sold out. Ni modo I guess.
I have a steam controller too and I find the placement of the thumbsticks and face buttons awkward so I tend to use the PS5 one instead, and I don’t find the trackpad placement on it too bad. steam controller trackpad placement is definitely way better though.
