"Vikings" Season 3 is currently under prodcution will have a release date sometime in the summer of 2015. You can watch the Comic Con trailer below.

The History Channel renewed the series for a 10-episode third season on March 25 earlier this year.

The most recent news is that Athelstan, played by George Blagden, may be dying this season. Or at least one major character will die this season.

Blagden recently accepted the role Louis XIV for a miniseries, and this many are speculating that he took this new role because his role on Vikings will disapear due to his Athlestan's death.

"Athelstan is one of those characters who has an effect on everyone else. For Rollo, it was anger. For Floki, it was maybe jealousy. And for Ragnar, it was curiosity," Blagden explained to Spoiler TV. "The fact that we see Ragnar even considering to engage with the worship of a foreign god at the end of Season 2 is really powerful, and ultimately that was Athelstan's influence. I can't wait to see where Michael takes Ragnar with this this season."

In season 3 you can expect to see more from Bjorn," It's definitely been a coming-of-age story," Lugwig, who plays Bjorn, explained to Zap2It. "Historically, this character goes on to do some pretty incredible things, so I think we're setting up him coming into his own and becoming a man."

"You just read these great scripts [by Michael Hirst] and he's already implemented that slowly in the third season and you'll see that," Ludwig told TV Fanatic at the 2014 San Diego Comic-Con. "He was a boy in the second season and I really tried to play that...and in season three he's a man. You see him learning and really taking after his father."

Members of the cast and crew made apperances during the San Diego Comic Con and gave an interview to Yahoo! TV a month ago, revealing a few details about the next upcoming season.

"It's only going to get grittier, and I think that's why fans are absolutely in love with it right now," said Alexander Ludwig, who plays Bjorn in the series.

Katheryn Winnick, who played Lagertha, said, "Season 3 is even more epic than Season 2. If you thought you loved Season 2, Season 3 just takes it to a whole new level," Winnick said.

"We had some shield maidens last year that went into full-on martial arts training just to understand how to hold a sword properly, just so they could be background actors," she added.

In the recent San Diego Comic-Con, series creator Michael Hirst revealed that the upcoming season will feature the biggest adventure that Lothbrok and has faced yet: The Great Raid in Paris.

"Yeah, we're gonna attack Paris. Paris was the most extraordinary city. It was still a Roman city, and it was like nothing else on earth. We're just building that, at the moment, on the backlot. It will also be CGI. Ragnar attacked Paris with one hundred ships," he said in the interview with Collider earlier this year.

"We go back to the raiding thing this year instead of all the dramas in Kattegat," Fimmel was quoted saying in an interview. "So, we'll be back together raiding."

Several new actors will be joining the cast of "Vikings" for season 3, including: Lothaire Bluteau as Emperor Charles of France; Jennie Jacques as Judith, mother of Alfred the Great; and French actress Morgane Polanksi as the Emperor's daughter Princess Gisla.

TV Guide also revealed other mysterious characters who will add more excitement to the drama. There's Harbard, who will catch the attention of Siggy, Aslaug and Helga, and Kalf, whom the Shieldmaiden Lagertha (Katheryn Winnick) has entrusted her dominion with while she sailed off alongside Ragnar.

Another interesting spoiler that has emerged concerns the death of a fan-favorite character. Even though it has not yet been revealed who is going to die in the next installment, actor Kevin Durand spoke to Entertainment Tonight Canada about it.

He said, "Do you know how that happens? Did you know that I was there? When the person dies ...yeah, I'm on Vikings... it might have been my fault..." Durand said

Durand told interviewers revealed that he will be playing mysterious wanderer character, he can either be a wreak havoc or be a poet.

Season 3 will also deal with Ragnar assuming power and the issues involved with that. "The first scene starts out off with all the trouble that power causes," Fimmel said at the 2014 San Diego Comic Con, according to Nerd Repository. "I think throughout this year it really becomes alive, how hard it is to be a leader and all the sacrifices you have to make and all that sort of stuff."

"Vikings" season 3 is coming in the summer of 2015, check back for more information as we get closer to the release date.
