As much as I hate to say it, I think Star Trek actually is dead. The one thing they could do that I think would work is something post TNG post DS9 post VOY, actually continuing the series. I mean the endings of those series still left a lot of momentum. And they seem to refuse to do this, ala, Enterprise. I would absolutely love to see another trek, but I just don't see it happening.
I for one would LOVE to see another TNG-esque exploration series, maybe with some familiar faces like Will Wheaton (Wesley) and Aaron Eisenburg (Nog). Maybe even throw Alexander Roshenko in there. But I just don't see it happening. Here's hoping I'm wrong!
