This wishful thinking from the TNG cast always makes me a little melancholy. Those guys had a chance to build a viable motion picture franchise and they never really brought home the gold bullion like the Classic Trek films did. That they think there's any chance of making a comeback after two duds in a row is just... sad.
Or perhaps, pathetic?
The TNG characters are strictly small screen fare. If they ever return again you can bet it'll be a tv movie reunion. I doubt Stewart would agree to that but I bet Frakes would.
