Know anything about the new evolve boards coming out in 2021?

Been hearing around that evolve is testing out new boards that should be coming out within the next 8-10 months, supposed to be a 60km/h to 60km range spec. Or possibly 50km/h to 100km range, as well as a hot-swappable battery. Know anything else about it??

 

New battery tech? Otherwise the board will be excessively heavy due to a much larger capacity battery. An average 18650 cell is ~45gm. I think the battery is a 10s4p set up. Cells alone = ~1.8kg. The boards are heavy enough as is. The combination of mega torque, speed and range would require significant energy to power probably a larger motor.

Check out unknownboards M5. Supposedly ~60km/hr sustained speed, but I think they noted ~30km range.
