Now that Charlie Sheen has been fired from CBS' hit sitcom 'Two and a Half Men,' about the only thing that's certain is that the actor won't have to put on a vertical-striped shirt ever again (or, as he puts it, "for as long as this warlock exists in the terrestrial dimension"). But so much else remains up in the air.

Can TV's most popular comedy continue without TV's highest-paid star? Will John Stamos or Rob Lowe (or another player to be named later) replace him? What sort of financial consequences is CBS facing if the lucrative, eight-season hit grinds to a halt? On the other hand, would it still be profitable to keep an aging, Sheen-free show going for a ninth year?

Below, we'll try to answer these and other burning questions about what's next for a network suddenly drained of tiger blood.

When the San Diego Comic-Con opened its doors to allow every corner of television onto their floors, they weren't kidding. After seeing the roster of panels, I'm surprised the original panel from PBS's Washington Week didn't field questions from guys dressed in Transformer cosplay.

Apparently, Warner Brothers set up a panel for just about every television show that have in development including Patricia Heaton's new ABC sitcom The Middle, making it the most "fish out of water" selection for a panel at the geek confab.

And so did the geeks in attendance. The panel only drew around 75 attendees and studio heads ordered Heaton not to introduce the panel because the crowd was too small.

It seems like a no-brainer that television and Comic-Con would go together like peanut butter and jelly. But TV has actually been a bit slow to the game and viewed their presence at Comic-Con as something that goes together like peanut butter and regular butter (trust me, I've tried peanut butter and butter, and it's not good).

This year, studios have recognized the importance of the annual geek con-fab and are presenting more shows and panels than ever before. There is going to be more TV at the Con than you can shake a stick at, so don't forgot your shaking sticks.

Why so many? Variety reports that studios and networks are recognizing the buzz they can generate at the convention through electronic social networking and good ol' word-of-mouth by showcasing and premiering exclusive screenings of their shows.

Okay, enough already! Personally, I'm glad that the grass roots campaign to save Jericho turned out well, and I think that the Mars candy bar campaign to save Veronica Mars is cute, but a futile attempt (at least according to show creator Rob Thomas). But, when a television studio tells you to sign a petition to save a show that the network didn't seem to really want in the first place you're going a bit too far.

The studio I'm talking about is Warner Brothers Television, and the show I'm talking about is ABC's Traveler. We actually received an email from someone over at WBTV promoting an online petition asking for a second season of the show, which has done okay since its premiere. The petition says that 8 episodes of the show aren't enough and the network should consider bringing the show back for a new season. As I write this there are 513 signatures, which is probably not enough to send to the programming wonks over at the Alphabet Network.

Sister is doing it for herself. When Gilmore wraps and the Studio 60 guest spots dry up, Lauren Graham will be able to fall back on her production chops. Graham has unveiled a slate of shows that she'll be executive producing with Warner Brothers Television under the banner of Good Game Entertainment. Good Game Vice-President Kathy Ebel is a college friend of Graham's, and the Warner Brothers' partnership is good so long as Gilmore Girls is on the air.

What's on the Good Game girls slate so far? First up is an international auction house-set dramedy called Objects of Desire. The show, which has been sold to The CW, is an ensemble show that promises a mix of "juicy workplace soap and behind-the-scenes intrigue" as well as a procedural element that follows an art object's history over the course of the show.
