FYI I just had a chance to try Zwift with the new Bluetooth support (needs iPhone app), and was able to successfully pair it to my HR strap, cadence meter, and perhaps more importantly, my Kurt Kinetic inRide power meter pod. So for the first time, I'm actually able to propel myself down the road in Zwift (I have no ANT+ dongle). It requires some steps as it's in Beta, but it looks like Zwift will soon support this setup well.
Caveat about the inRide: I tried it with the v1 pod. The v2 pods (which presumably come included in the new trainers) may not work.
