The question of questions: Will there be a third season of Supernatural?

Okay, okay. Call me weird. I know that there are still 9 episodes of SPN's 2nd season left but the not really good ratings of this show got me thinking...

( I'm not sure if you consider my spoiler-free musings about the possible existence or non-existence of SPN spoiler-ish, but I'm cutting them, just to be safe )
