TE,
I'm not so sure about that. I read an article in the newspaper and they basically said that one of the other TV series would be next in line for a movie. Either DS9 or Voyager crews would make excellent movies....
They said that Nemesis would probably be the last TNG movie...but they also said 'never say never'.
It stated that each movie costs aprox. 45Mil to make and each one has consistantly grossed over 95Mil.....so it's very low risk to make more....
Well, it might be the last TNG movie, but I definitely see SOME sort of ST movies in the future...
