I have recently purchased the 65 inch oled a1 tv with the Ht-st5000 soundbar and two SRS-ZR5. Will sony be making it possible to set up a true surround sound system linking these together.

I am disappointed that this is not already available, with sony's high end soundbar.

I know the Ht-st5000 can bounce the sound off the ceiling to provide a surround sound effect, but surely having actual rear speakers linked to the Ht-st5000 would give a superior sound quality especially now the Ht-st5000 has recently been updated for Dts surround sound. 

Please Sony update the Music Centre to allow surround sound grouping of wireless speakers  to work with your premium Ht-st5000 soundbar. I know that surround sound works with some of your other wireless sound ars

 and the SRS-ZR5 speakers.
