Entertainment Weekly said 2012 could be the "geekiest year ever" with possible panels for:
The Hobbit
The Dark Knight Rises
The Avengers
The Amazing Spider-Man
Man of Steel
Prometheus
the new James Bond movie
The Lone Ranger
Hunger Games
Abraham Lincoln: Vampire Hunter
Clash of the Titans 2
Jack the Giant Killer
Some of those just outright won't happen and others are very unlikely. The Avengers will already be out before SDCC, as will Spidey, which had a panel this year. I think TDKR comes out around next year's SDCC and they never had a TDK panel so I doubt they do a TDKR either. I think Prometheus had a panel this year already too. So EW doesn't know jack.
