OH [tornado fang] YOU, CHUNSOFT. Zero Escape 3 is seeming very unlikely, according to the creator. The series isn't popular in Japan, though it's very popular in the west. However, since it's a Japanese franchise, the higher-ups care about Japanese sales, first and foremost. And those sales aren't looking too hot. D:
[tornado fang]. So many people had there heart set on Z3 (I know I sure as hell did), and now it's unlikely. Uchikoshi (the creator) was actually extremely nice to the fans, and expressed his desire to make volume 3. He pretty much always spoke with them and answered their questions.
What the [parasitic bomb] is it with trilogy titles getting cancelled/postponed?
I recall seeing that on a thread at SA, apparently lots of people responded with posts or pictures expressing their desire to see a 3rd game.
But yeah, if Capcom has taught us anything its that Japanese companies seem to give little care if something is popular outside of their home country.
