My guess is a pre-built PC or AR device. Latter is more unlikely since it would substantially overlap with their Index market.
EDIT: A PC makes more sense given the strides they’ve made with Proton recently.
Another idea is a platform for in-place movement while using the index? Seems a little more out there given VR has fallen off the map a little recently.
Good budget(ish) switch to get a good phone, privacy, security, and AOSP experience.
