So it's about time that we started getting an idea of just which mega-movies will be on hand for the festivities, specifically those having presentations in the legendary and massive Hall H.  Universal Pictures is a maybe at the moment, while DreamWorks Animation, Paramount Pictures, and 20th Century Fox are all sitting this year out, according to Variety.

Fret not, however, as Marvel Studios and Disney will be in Hall H, along with presentations from Sony Pictures, Lionsgate-Summit Entertainment, and Warner Bros., are all bringing the thunder.

Let's break down just what attendees are likely to see, shall we?  Yes, yes we shall.

Marvel Studios previously used Comic-Con to great effect, drumming up anticipation for Jon Favreau's Iron Man films and unveiling the full cast of The Avengers in 2010.  In order to prop up Disney's D23 Convention, Marvel skipped Hall H last year, but this year, the heavy hitter's back.  Marvel is pretty much guaranteed to bring something fun from Iron Man 3.  The film has only been in production for a few weeks now, so don't expect anything too flashy; maybe some rough footage of dialogue scenes and the presence of director and co-writer Shane Black, probably along with some castmembers.  It's also possible that Marvel Studios will use the opportunity to announce the title of the mystery movie scheduled for May, 2014, as well as other projects down the development pipeline.

Beyond Marvel, Disney will probably debut some material from Wreck-It Ralph, given that the clever animated adventure takes place in videogame worlds and the Comic-Con crowd is generally down with that.  Sam Raimi's The Wizard of Oz prequel Oz: The Great and Powerful starring James Franco could also get teased, along with Gore Verbinski's The Lone Ranger, which the studio is doubtless hoping to prop up after recent news about the production.

Sony Pictures is planning something for Hall H, but don't expect the studio to bring along The Amazing Spider-Man, since the movie arrives on July 3rd.  Some very early footage from Len Wiseman's Total Recall remake seemed to impress the crowd last year (either that or they were simply distracted by Kate Beckinsale and Jessica Biel onstage), so perhaps that film, set for August 3rd, will be pimped a bit.  David Koepp's Premium Rush is also a potential presentation subject.  Same goes for After Earth, the M. Night Shyamalan science fiction film starring Will Smith and Jaden Smith.

As for the recently-merged Lionsgate and Summit Entertainment, something for The Twilight Saga: Breaking Dawn - Part 2 is guaranteed, probably including clips.  The Twilight panels have drawn big crowds the last few years, much to chagrin of some non-fans at the convention.  To balance things out, the hyper-masculine shenanigans of The Expendables 2 might just get showcased, too.

Warner Bros. has never once thrown down a San Diego presentation for Christopher Nolan's Batman films, and The Dark Knight Rises won't be the exception.  Yeah, it hit theaters less than a week after Comic-Con wraps up, but the anticipation behind the sequel is such that it doesn't even need Comic-Con.  DC's other big hero is likely to have his moment, however.  Man of Steel director Zack Snyder held down at past Cons with 300 and Watchmen presentations, so this year's event will probably feature the first footage from the Superman reboot executive produced by Nolan.  The studio has reserved a whole three-hour chunk of Hall H time for Saturday, so Comic-Con demigod Peter Jackson will undoubtedly be on hand to tease The Hobbit: An Unexpected Journey, perhaps giving the crowd its first taste of 48 fps 3D.

Teaming up with Legendary Pictures, Warner Bros. is also expected to debut some footage and goodness from next summer's Pacific Rim, the science-fiction monster epic from Guillermo del Toro.  The loquacious, foul-mouthed, and endlessly entertaining Del Toro is like royalty at Comic-Con, and he'll sprinkle his charm whilst hopefully showing off what he's promised will be monster movie to end all monster movies.

Stay tuned for more the happenings at San Diego Comic-Con 2012, folks.
