What? No. The Tempest chip is their alternative to Dolby Atmos. It's there since day one, it has a headphone and a TV version and it'll have a soundbar version. You're 100% wrong here.
I referenced "discrete surround sound systems", not headphones, TV's, or Soundbars. I'm talking about the discrete multi-channel variant of Tempest which was intended to virtualize the "height" and "sound bubble" effects of real Atmos with a proper 5.1. or 7.1 bedlayer.
The Tempest portion of his Road to PS5 deep dive video (last 15 or 20 minutes or so). IIRC he refers to it with some variation of "we hope to", and "if we can get it working".
