This is great news
PPG WAVE (and especially the old 2.0) is my single most wanted synth. It is the only synth I regret I did not buy when I had the chance to have it for a relatively reasonable price (long ago).
I really hope they nail the sound of the old machines, otherwise it does not make sense to clone it.
None of the Waldorfs or plugins have the raw sound of the PPG. The only thing that sounds like it, is the Kotelnikov euro vco (but that is only one voice without filters vca, etc).
