I'm sure one's already been signed hasn't it?

For some reason I fear that it would be the last season though... don't know why, just a feeling...

I really hope there is.

yea i hope there is to

Of course there is!season three isn't enough time to tell everything that is happening in supernatural and I really hope there is a season 5 coz i don't want supernatural to end and Ill be more than sad if it does!i'll miss watching them :(

Man,i freakin hope there is,Supernatural is the greatest.EVER!!!

here's link and here's the specific question below
i think this means a season 4...

If we don't get a full Season 3, what would happen with Dean's deal? Would the big climax be in the middle of Season 4 or would it be extended to the end of Season 4? — acsgrlie
Kripke: That's a very smart question, and one that's currently haunting my dreams. There's a simple answer: We'll definitely save the climax of Dean's Deal for Season 4, no question. And there's a more complicated answer: Not many showrunners will admit it, but the strike is throwing a lot of stories on a lot of different series up in the air. I mean, how do you get back on the story track in an elegant, artful way? If I had to guess, I'd say I'm probably going to end up combining the Season 3 and Season 4 mythologies into one big story to play out next season.

so there is another season coming :D...awesome!

they are saying that their taking it off and making a comic about when they were kids learninghow do hunt(crap what bout jensen and jared)
