The latest issue of SciFi Now finally has a decent article about Supernatural, a Q&A with Jensen, Jared and Eric Kripke. There are a lot of spoilers for season four in the article. Nothing I'd consider major spoilers (a couple are maybe medium); for the spoilerphobes like me I've included de-spoilered scans, too.
Apologies for my crappy scanner.
But there's more! They've also got a nice long article on the upcoming Watchmen movie with Jeffrey Dean Morgan. This one, I haven't de-spoilered :-)
ETA: Feel free to share or repost the scans.
