As I understand it, Oculus Touch is intended for two front-facing trackers (it comes with a second tracker to go with the Rift tracker). And the tracking seems pretty good while you're facing them. However, the three-tracker and diagonal-tracker setup is experimental, and the diagonal-tracker setup (Vive does the diagonal-tracker setup with its "lighthouses" to enable room-scale) is necessary if you're going to have games that encourage you to turn around or otherwise occlude the headset and the Touch devices with your body.
