Like others have said, the new and improved Enterprise was too little, too late. It's a shame to see the Star Trek franchise go out on a whimper, but I'm sure it'll be back again one day. (Hollywood is pretty repetitive.)
My bet is that a few years down the line, we'll see a new Star Trek movie with a brand new cast, to test the waters. It may or may not be a remake of Kirk and the original crew. What I'd rather see is an anthology style TV show, like Outer Limits, set in the Star Trek universe. They could have a few stories set in the Academy, a couple with Klingons, or Vulcans, some stories following up on the Voyager people back on earth again, and brand new stuff. An anthology style show allows for big guest stars to do an episode or two, as feature characters instead of a minor role.
