I agree with you... we are waiting from at least four years only an update for PHP7 but nothing is still arrived... DMXzone releases new extensions every (almost) week and they're working on a new editor (Wappler), maybe is arrived the time to see their products.
I think that behind these WebAssist delays there is something more that we don't know (otherwise Ray already has would show us a roadmap or timeline). I think that WebAssist is dead, only the official announcement is missing but... maybe I'm wrong, hopefully...
