Valve has openly stated that they only work on things that interest them, which is why unless there is some interesting new technology to play with (like they played with VR for Alyx), there will be no HL3.
I can totally see them chasing the shiny and dropping VR to focus on Steamdeck as the new Shiny, and then dropping Steamdeck to focus on whatever the new technological shiny is after that.
I genuinely don’t understand why the admins are dragging ass and not just defederating from them already. They provide nothing of value, just spam and harassment.
