We’ve got some sad news for you fans of ABC’s “Marvel’s Agents of S.H.I.E.LD.”- the series will be ending with season 7.

Jeph Loeb, Head of Marvel Television, spoke with Deadline about the decision, which will more than likely be announced during the “S.H.I.E.LD.” panel at SDCC today.

“The simplest answer is so that we can end on our terms, really. How many shows do you know that just suddenly ended, and you feel like, but wait a minute, there was more. Yes, in the chronology of this is we thought Season 5 was the end. If you go back and you look at the end of that season, it is written that way. Actually, the last episode of that season is called “The End.” Honestly, we thought we were turning out the lights and going home when we got a call from ABC that said, the material is so strong, do you think you have another season, do you think you have another 13 because we sort of like this idea of doing it again.

Jed Whedon and Maurissa Tancharoen and Jeff Bell, who have been there from the very beginning, went away and came back and said, we have a cool idea. That cool idea became Season 6. The show started to come in, then about halfway through that season we get another call from ABC’s Channing Dungey, who is a big fan of the show, super supportive, and she says, how about a Season 7?

Everyone is making plans, like it was at the end of Season 5, we thought it was done. Then we, again, sat down with Jed, Jeff, and Maurissa. We all came to the conclusion that getting another season is so flattering, so lovely, so amazing, but how about if we go back and say, yes, but this is it. So we can actually build a season that will tie up any threads that are there. To make sure that we come to a conclusion that’s satisfying to the fans, to the cast, to Marvel, and to ABC.

When you know that’s what you’re doing, you can take greater risks, of life and death. Those kinds of decisions suddenly now are real on the table because you’re not playing how do we undo this when we get to the next season. You’re playing that this is going to be the end of the story.”

UPDATE- 

A new trailer for the backhalf of season 6 was released during the show’s SDCC panel:
