Just saw these announced on the Casio International website.
It's an anadigi with Bluetooth but no solar. It also has some new features with the Bluetooth connection allowing it to do notifications for scheduled start and end times of events on a calendar. Can also automatically correct to local time when changing time zones, not sure if previous Bluetooth watches did that.
But possibly the most interesting thing about it is the octagonal bezel, probably influenced by the popularity of the GA-2100. I feel these look even more like the Royal Oak with the metal body and screws. Funnily enough they market it as "The watch face features an octagonal bezel studded with four screws, evoking a professional power tool used for racing car maintenance."
Measurements are 51.0×48.5×12.5mm, and will be available in 5 different models (can't post links yet so add a www at the beginning: casio-intl.com/asia/en/news/2020/0122_ecb-10/ )
Personally I think they look fantastic, just a shame no solar battery.
