The "cheaper consumer version" focus for now seems to be on the Windows 10 Mixed Reality goggles coming out in the Fall. Yes, it's not HoloLens displays (it's classic LCD screens strapped to your face) or standalone computer (it's tethered to a PC), but it is cheaper and it will be consumer focused in the Fall (and it will use most of the same Windows platform support and niceties like inside-out tracking).
