I never watch Star Trek, but it's a great theme. Paramount owns and operates Star Trek: The Experience in Las Vegas, and that seems to be doing really well. It really does make a great theme - Star Trek is to Paramount as Star Wars is to Disney.
I'm not too worried about the theme, and I think Paramount will do a good job with theming for whatever they do choose. If it be Star Trek or Tomb Raider(or even Airplane!), then let it be, I'm not going to fight it or whine about what it should've and could've been.
