It hurts when a TV show that you've been watching for years ends on a cliffhanger and then gets canceled. It really hurts.
So...it's nice to know that the people involved with the show feel the pain of the fans.
Show runner Gary Scott Thompson, now attached to NBC's Knight Rider, has come out and said that, "We're actively trying to figure out how to do something."
Cast members Josh Duhamel and Molly Sims would also be on board. Says Thompson, "I talked to them both the other day, and they said we should do something. It was their characters that were really left hanging, and they were very upset by it."
Sadly, there are no definitive plans yet, though appearing in an online video or even having the Las Vegas characters appear in an episode of Knight Rider (since Rider is also set in Vegas) have both been thrown on the table.
