I seriously doubt there will be a new RPG coming. Maybe MW would do one but probably only for the new movie and with just a few supplements, meaning 1-3 books. Considering how small their support for BSG and Serenity is, I would hope they don't do a game ( although the games as such were quite good ).
But frankly I think Star Trek is dead - at least over here in Germany there is nothing left of it. There are not even any books coming up anymore and no book-shop I know - and I know a lot and good ones - has any, not even in English. If the new movie should be ablte to revive the genre ( which I think cannot be achieved without the major part of the already existing fanbase ), then maybe we will get another movie or series and for that we might see a new RPG.
On the other hand I think we do not need a new RPG.
