Well it’s not the new Korg Wavestate SE. That now has channel-aftertouch but not poly, though it does have poly note-off velocity apparently.
I actually had been supposing a Korg series product with Poly AT ( including a new version of the OPSIX ) to be a possibility just a couple days ago, but that looks like that is a NO.
I also thought of a list of other possibilities, but rather than turning this thread into a speculation thread, based on what nightshift2020 reported, perhaps we need a new “Poly AT Speculation Thread” ?
