@Captain Craig...this is an interview/article with Rick Remender that you might find interesting and should address any concerns/questions you might have regarding the current Circle of Four arc and "Venom" in general. This was from early December.
As for Ghost Rider...I believe the original cancellation notice came just prior to the law suit being settled. I don't know if this changed things or not since Marvel won it. It's possible they rescinded the cancellation after it was settled. I really don't know. I haven't seen anything about it being continued. Also with the film coming out...it makes sense for them to push out a couple more issues.
