According to Michael Ausiello:
* Tom Welling will be there! The show’s leading man and exec producer will be making his second appearance at the Con.[Ausiello Files]
* Welling will be joined by returning series regulars Erica Durance, Cassidy Freeman, and Justin Hartley at the show’s panel on Sunday at 10 am.
* Showrunners Kelly Souders and Brian Peterson will also be present to answer all your burning question about the show’s 10th and final season.
* Did I mention acclaimed Smallville writer Geoff Johns will be moderating said panel discussion?
* Last but not least: You’ll be treated to an exclusive first look at the season premiere!
The panel will take place on July 25th. I may go take a peek if it doesn't conflict with anything else since this will be the last time Smallville will have a presence at Comic-Con since the show is entering it's final season this fall.
