Valve appear to have some pretty ambitious future plans for Steam, as we've seen recently a leak (and not for the first time) that Valve has plans for ARM64 and Android support on Linux.
Yes it is, so theoretically people can just install Arch with KDE and Steam and get a similar setup. However, there is something to be said about a supported OS versus Arch Linux’s community support which tends to have little patience for people who aren’t well informed about the workings of their OS.
They mean when will Valve release an official Steam OS 3 ISO that we can install on our own PCs.
Isn’t Steam OS currently built on Arch?
Yes. But SteamOS is immutable.
Yes, and ChromeOS is built from Gentoo. That doesn’t mean much, the end user experience is worlds different.

So, go with garuda or endeavouros, they have great installers and the community is pretty supportive.
