I think I got hit with the same Beta change yesterday afternoon. Just when you have it how you like it, they mess it up.
As to heating up, some have already said this, but the Photo Cover for Sex Criminals #1 has been doing great for me.
Sales between $10-$12 2 weeks after it came out is pretty good (esp when you find them for cover). As long as people with big orders coming in at the end of the month know how to ration sales accordingly, should be good for some time.
Also, may be one of the best recent covers for an SS.
