This years‘ Oculus Connect appears to announce the Santa Cruz stand-alone system, one which really intruiges me quite a bit (while the Go could not raise any interest as it offered something comparable to the GearVR which I never cared about either).
Lower graphics performace than a PC based system of course, but autonomous world-scale true 6DoF with VR controllers, that could really be a treat.
However, that would pretty much mean that we will not learn much, or rather nothing about the Rift 2. And I would not be astonished if that only releases somewhere in 2020, being announced during Oculus Connect 6 in 2019.
If they want to wait for so long to consider a consumer version of the Xtal, it may have become obsolete by other manufacturer‘s products in the meantime though.
