"Not possible before." This one is literally true though. They had a semi-custom chip designed to implement features/performance that don't exist with Bluetooth 4 yet. I think Bluetooth 5 will catch up. In fact, I'm betting that what they have is basically a radio chip designed for Bluetooth 5 (it's basically just Bluetooth LE with higher bandwidth and range) with some extra features for their pairing tech, but since the spec wasn't finalized, and they couldn't wait, they just rolled it out as proprietary tech.
