'Dexter' may be leaving us for good in the next few months, but you didn't think Showtime would let our favorite serial killer go without a massive Comic-Con 2013 panel blowout, did you? 'Dexter''s final season will headline the show this year by debuting on opening day, Thursday, Jul. 18, movin' on up to the 6,000-seat Hall H. So, who from the cast and what top-secret guests can we expect on the table panel?

'Dexter' fans at Comic-Con, this is your year! Not only will series stars Michael C. Hall, Jennifer Carpenter, David Zayas, James Remar and returning Yvonne Strahovski be present along with executive producers John Goldwyn, Sara Colleton, Scott Buck and Manny Coto, but the 'Dexter' final season panel will also include some surprise guest stars "too big to mention"!

Our gut tells us that might include Julie Benz and/or Jaime Murray, both present at the event for the 'Defiance' panel, or potentially Jimmy Smits, given the 'Sons of Anarchy' event, but let's not forget about the Trinity Killer himself, John Lithgow! Lithgow lends his voice to the white rabbit on 'Once Upon A Time In Wonderland,' and who better to grace the final 'Dexter' panel?

'Dexter''s Comic-Con appearance will take place Thursday, Jul. 18 in Hall H from 6:30 p.m. to 7:30 p.m., and we'll be on hand to bring you the latest on the final season! Tell us what you hope to see from the final panel, after the latest 'Dexter' preview below!
