Hi @Jackmac1216 

Hold on, I will consult Professor Sybill Trelawney.

Seriously, unlike TVs where Sony launch new models every year, new Sound-bar models are kept very secret.

They would never advertise a replacement product and compromise sales of an existing product while they selling well. As the HT-ZF9 is now over 4 years old one would hope so. I bought mine with the SA-Z9R rear speakers back in 2018 and have since sold it.

People have been speculating about a HT-ZF9 replacement since 2020.
