The Space Shuttle was named Enterprise because of Star Trek, not because of any prior usage of the name.
ST Online was in development hell for a little while but it came back out. I hope the game does okay. Star Trek has been dying for a long time. The recent Star Trek movie brought it back to life a little but I dunno if the movie revitalized the franchise or was just another popular popcorn flick that rakes in money and gets forgotten.
