Quite so. There are any number of ways they could celebrate the anniversary without rushing a film. A touring mega-convention with everyone they can get to attend. A screening event of the extant movies like they did for the 25th anniversary--perhaps presented in various cities by Trek alumni. The kinds of things hardcore fans will attend (and they're the only ones who will really care about the 50th anniversary). People compare it to Bond's fiftieth, but that's a false comparison. Bond only has the films, really, while Trek has a lot more.
