Question New MPPT Solar Charge Controllers Upcoming?

Love the FlexBoss announcement it has everything I need while looking for new SCC for my parents old off grid setup. Since we already have an old inverter, and my parents would be loath to get rid of something that wasn't broken, I was wondering if maybe the EG4 MPPT 500v 100-48 might be seeing a refreshed model?

Would love to see the specs of the FlexBoss MPPT (600v, 3 trackers, higher input amps) in its own standalone MPPT.
