It's not as if there had been any doubt that ABC and Marvel's Joss Whedon-directed 'Agents of S.H.I.E.L.D.' would prove the Comic-Con 2013 TV event of the summer, but at last we have confirmation of when and where fans can fight to attend the official panel. Additionally, ABC's 'Once Upon A Time' spinoff 'Once Upon a Time in Wonderland' will make its presence known, but who from either series will show up at Comic-Con 2013?

The 'Agents of S.H.I.E.L.D.' panel will reveal itself to the world on Friday, July 19 with appearances from executive producer Joss Whedon and Marvel’s Head of Television and series executive producer Jeph Loeb, though it remains to be seen if the pilot will actually screen during the event. The ABC series will also be spotlighted at the Marvel Entertainment Booth on the Convention Center floor throughout the weekend, with "special surprises" to be announced.

Among ABC's other new offerings, 'Once Upon A Time in Wonderland' will join its parent series for a panel on Saturday, July 20, with both casts in attendance participating in panels, autograph signings, and more.

You can bet that we'll be on hand in San Diego for all the inside scoop, but in the meantime what say you? Are you excited to see what Marvel's 'Agents of S.H.I.E.L.D.' will reveal at Comic-Con 2013? Give us your predictions for the event of the season in the comments!

And hey, let's watch that trailer again!
