That's what I'm talking about. If people adopt FBT like Valve's (HTC, Tundra, or others'), then Oculus will have more reason to get into FBT, just like how they have no reason to come out with a Pro model right now (not a PC VR model, but a Pro mobile model), but if the market gets big enough that even a niche segment of this "niche" becomes a good source of revenue, then they might do it, and apparently they will. If people don't adopt that FBT, then Facebook absolutely won't invest in that.

And it's not going to be a power/technological problem, I'm not sure why you would think that. The headset's battery life wouldn't be impacted. The pucks would have cameras on them and run inside-out tracking on them, which can be accelerated by a dedicated ASIC. The image data wouldn't be transmitted, it would be processed on the pucks. That also gives the advantage of power savings because you can integrate the ASIC close to the camera sensor. 

Even if we try prototyping early versions of it right now, we could get at least 2 hours from a full charge, because we know Quest itself can already last that long, and that's while running games, running the screen, running controller tracking, and doing other processing. A dedicated puck could easily do 3+ hours which will outlast the headset, and we can still connect powerbanks if we want. And that's just today. Facebook would not get into this business any time soon, so by the time that FBT is something that is profitable, there would be better and more efficient software + hardware to do SLAM.
