Surround speakers Samsung swa-9000s/en discontinued? Will there be a replacement?

[Achemson2003]

Hi everyone,
I just bought and installed a new Samsung hw-Q70T soundbar, which is a 3.1.2 model. I specifically bought this soundbar so I could expand it into a 5.1 system with the rear speakers suggested in the manual or in the site of Samsung, the SWA-9000s/en ones. The problem is, I started realizing that they are out of stock everywhere in my country (Greece) so I called Samsung here and they said that the speakers are no longer produced by Samsung, so I should buy them from somewhere as long as stock remains. How is it possible to officially suggest pairing a newer soundbar with speakers that are discontinued? 
Does anyone know anything about it, or if there will be a replacement model?

Thanks in advance.

I wondered if anyone knew of a test video or something I could test the speakers and sound bar to balance everything .. I mean ideal settings for back,front, rear , just to set them up??
