Good points, everyone.
I guess I can look at my own behavior as well: I had a little bit of money recently for cards and rather than getting a few from some of the artists I mentioned, I got several really nice ones from lesser known artists and sets.
When you list out all the products that have come out recently, I guess it's no wonder there's a good bit of buyer fatigue at the moment. I have to confess I have almost no interested in some of the new comic releases coming soon beyond my specific PC characters.
