Even though the production schedule means that 'Game of Thrones' won't have anything of season 3 to show at Comic-Con 2012, we can barely contain our excitement to see our favorite stars gather together to discuss the show with the fans. However, a last-minute schedule shift might change which actors actually appear on the panel, and who might be brought in to replace them!

Thanks to Entertainment Weekly, we've now learned of a minor shift in the 'Game of Thrones' panel at Comic-Con 2012. Unfortunately, scheduling conflicts will prevent actress Lena Headey (Cersei Lannister) from making the panel as in years prior, which will this year take place on Friday, July 13 in  Hall H from 2:45 p.m. – 3:45 p.m. Instead, actress Rose Leslie (Jon Snow's new lady-friend Ygritte) will join the panel, which already includes Alfie Allen (Theon Greyjoy), Emilia Clarke (Daenerys Targaryen), Kit Harington (Jon Snow), Michelle Fairley (Catelyn Stark) and Richard Madden (Robb Stark).

But that's not all! Rumors continue to swirl over castings for the third season of the George R.R. Martin-adapted series, which will debut sometime in April 2013. The latest hearsay suggests that Tara Fitzgerald will be cast as Selyse Florent (Stannis Baratheon’s wife) and Mackenzie Crook ('The Office' UK, 'Pirates of the Caribbean') could be a possible Vargo “The Goat” Hoat.

What say you? Are you excited to see what 'Game of Thrones' season 3 has to offer at Comic-Con 2012? Will Ygritte have more to say than Cersei Lannister? Sound off in the comments below!
