It's all still very vague. Back in 2021 there was an article saying that Valve had 2 different designs, one was similar to the Index and another switched to Q2 style inside-out tracking. As far as I know that's the most we've heard about tracking methods since then.

There's something standalone about it but that doesn't neccesarily mean a standalone headset like the Q2 or a Steam Deck slapped into a VR headset. Evidence points to a Qualcomm chip being present in a prototype. Even if Deckard included Steam Deck hardware it could be indicitive of dedicated chip for handling wireless or other system tasks. Apple are rumored to doing something similar so it's not unreasonable to think Valve might have reached the same conclusion. Seems that wireless wasn't as easy as Gabe said back when the Index launched.
2022 patents as well as codenames in steamVR files suggest that native wired may remain an option too.
