The 2011 San Diego Comic-Con is just over one month away, and, while we still have to wait a few more weeks before the official schedule is released, several studios appear to be skipping out on the annual event this year.

Studios such as Warner Bros., Disney, DreamWorks, and The Weinstein Company will not be showcasing any of their upcoming movies at this year's Comic-Con. And that means two of the biggest comic book movies currently in production, Man of Steel and The Dark Knight Rises, will be absentee when it comes to their presence at this mammoth fan-fueled event.

There isn't an official consensus on why these major studios are shying away from the convention, although some believe that movies which generate fanboy buzz at Comic-Con rarely translate into box office success. One example cited was Universal's Scott Pilgrim Vs. the World, which was released just three weeks after last year's triumphant Comic-Con presentation, and still only grossed $32 million at the domestic box office. Still, David Glanzer, Comic-Con's director of marketing, believes there is no big shift in studio attitudes towards Comic-Con.

"We get more and more requests, and have less ability to fulfill them. Not every studio comes every year."

There will still be plenty of big name studio releases which will be trumpeted at Comic-Con this year. Earlier today, we reported that Universal's Cowboys & Aliens will have its worldwide premiere at Comic-Con 2011, and Paramount is making plans to promote The Adventures of Tintin: Secret of the Unicorn. It is said that director Steven Spielberg may even appear in person at the event. Fox will roll out Rise of the Planet of the Apes and Sony has big plans for their The Amazing Spider-Man presentation, even though the movie won't be released until July 3, 2012.

Smaller studios like Relativity Media will try to capitalize on the larger studios pulling out. Relativity plans to promote The Raven, Shark Night 3D, and Immortals this year. Summit Entertainment is also planning a panel for The Twilight Saga: Breaking Dawn - Part 1.

There will be an even bigger TV presence at Comic-Con this year, it seems. Fox plans to promote 10 shows this year, with Warner Bros. Television bringing upwards of 16 shows to the San Diego event. The event has become an even bigger haven for TV promotion in the last few years, with the fall season just around the corner from Comic-Con. It doesn't seem that trend will change.

Stay tuned throughout the next month and a half as we'll be providing more updates about the 2011 San Diego Comic-Con as we get closer to the big event, which runs from July 20 through July 24 this year.
