The HTC Cosmos should be announced later this month which also has inside out tracking. I'm looking forward to seeing some head-to-head reviews of both headsets before I decide which to get.
I've been put off by headsets with higher resolutions due to the exra strain on a GPU but the new Oculus Rift S has a full 1440p screen with a lower refresh rate of 80Hz to compensate so it doesn't require a faster PC than the original Rift.
Apparently the Oculus Rift S has a narrower field of view than the original Rift which doesn't sound good. Neither does the downgrade from OLED to LCD. Although the screen door effect has improved a lot compared to the original Rift.
The 80hz thing is genius.
the loss of built in audio isnt.
the loss of non improvement of fov is also a big f up.
