I really don't know why Oculus dropping the support for GearVR in such early-stage since Oculus Go is the same as GearVR so they are not going to have wast too much time to support GearVR with new SDKs. And GearVR is the best place to develop your game first even if you are targetting Quest or Go, you don't need to put the HMD 100 times a day on your head to debug small little thing you made, you can do that in flat screen on GearVR, unlike Go and Quest. even if GearVR is dead which it isn't, its the best and easiest platform to develop your game for mobile VR, I used my GearVR tp publish my game for both Daydream and Oculus Go.
What's your thought about this? do you guys use GearVR too make your life easier for developing for Quest/Go?
