I see the current movie incaration of Star Trek running it's course very soon, especially with JJ and Company moving on to the Star Wars Uni - there's a whole lot more money to be made there.
As for Star Trek, I see it getting much smaller again. I think the fan generated projects will continue and become closer to mainstream, and I think (and hope) to see CGI films, either features, direct to homevideo, or TV.
Wouldn't it be interesting to do rotating schedule of (probably) made for TV CGI films featuring each of the crews - maybe one a month, or one per quarter? Then everyone could enjoy as much or as little of Star Trek as they wished. Ah well, probably not financially viable anyway.
