Apparently it is a real device and not fake or a scam like some were suggesting. It is currently being featured at Fosdem at the KDE booth even and it seems to be featuring the SteamOS interface but seemingly on a Manjaro based os.
I assume this means they have taken the HoloISO bits like the gamescope session and interface but rebased it on Manjaro but it could also just mean they forked and rebranded it as Manjaro (and possibly delay updates for two whole weeks in the name of stability).

It's the first linux first handheld device next to the Steam Deck and even comes with two touchpads that look strikingly similar to the Deck ones but never would I have imagined it being featured by Manjaro. The specs look impressive though the design reminds me of the early Steam Deck prototypes Valve showed once that equally featured a glossy finish.
Let's see whether it earns another entry on the list of Manjaro fuckups.
