Six for my sorrow

[cyrano]

So I'm hearing from semi-reliable sources that Supernatural is going for a sixth season.
I'm apprehensive for a couple of reasons. First, from the few episodes I've seen, fifth season seems to be God vs. The Devil. Where are they going to escalate from there?
Second, the boys both have six year contracts so they're back, but I've heard Kripke is stepping back--whether it's completely out or to McG's old executive producing spot, I don't know. Will they be able to keep the charm and atmosphere that got me watching in the first place?
Fingers crossed.
