'Supernatural' Season 11 is already brewing up a new set of episodes as word of its production hit various entertainment and TV news websites. This is a great announcement for fans worldwide, who are thrilled to find out about its new plot.

In the previous season 10 finale episode, the "Brother's Keeper", it was noted that the Winchester brothers (Sam and Dean) were both plunged into an eerie of 'Darkness' as the 'Mark of Cain' was successfully removed off of Dean's body. Such a scene has already set the pace of excitement for TV viewers who can't wait to see what's in store for season 11.

In a recent interview with CW president, Mark Pedrowitz, he confirmed that the upcoming season 11 will definitely not be the last, due to the show's high ratings.

He said, "I'm a big believer and a big fan of the show, and as long as the ratings hold and as long as the boys want to do it, we'll do it."

Meanwhile, Jeremy Carver, one of the cast mainstays recently gave thanks to TV viewers and fans alike and praised them of their support in watching the season 10 finale. However the actor went on to say that the upcoming season will both be darker for the Winchester brothers.

"We are so excited for season 11 and when we find out what happens when the darkness is released," said Carver.

Teasingly he added "For the boys,[Winchester brothers] things are going to go from bad to worse."

Carver's comments left fans wondering if he was speaking hypothetically or if he was trying to speculate at something that was bound to happen in reality.

Speculations on some of the casts not wanting to be on the show anymore had leaked out with recent emotional tweets from Jared Padalecki (Sam) came out on Twitter.  The young actor tweeted about being unable to make it to the show's promotion in Jibcon, Italy.

'Dear #JIBCON and #AHBL6. I am in desperate and urgent need of my family. I am so sorry to tell you this but I must head home,' tweeted Padalecki.

He added, 'I need all of the love I can get right now. Please please give me a few seconds of your time and write me.#AlwaysKeepFighting.'

It was reported that Padalecki had suffered depression in the past and had been known to have battled with it quite openly. It was also told that his depressing condition soon became common knowledge to his fans and to the public as well.

The actor's recent tweets only seemed to have sparked more doubts on the controversy that he might no longer be on the upcoming 'Supernatural' Season 11 show.
