The Steam Machine and Steam Frame are probably delayed, but they still intend to release them in the first half of this year.
They said they planned to have a concrete launch window and pricing by now, but hardware pricing/shortages have made that hard to pin down.
I used to think that would be a bad idea (because it’s very un-console-like to sell a device that isn’t plug-and-play out of the box) but I might be coming around on it a bit if it means a more affordable option.
They’d need to make it very clear to buyers, though.
