Cliff Olsen’s video is helpful. (linked from Abram’s post). They’ll have 5 models: 312, 312T, Rechargeable, 13T and a Rechargeable T. They become available the end of November, with Telecoil coming in February. It uses plain Bluetooth (don’t know what version and have no idea about battery usage. My reading of the artificial intelligence is that it was used to design them, not that they had it.
