Well, it probably doesn't HELP things with Anthrax - but I don't think it means anything bad either. The two CAN coexist - and Armored Saint is a sideproject to Joey Vera and some of the others as well, they all have other bands. They already stated in the past that their intentions with Armored Saint is to get together and have some fun and schedule a few odd shows here and there - they never have done big touring, and probably never will. I doubt Anthrax will be slowed down by this IF John rejoins. And it won't negatively affect Armored Saint if John rejoins Anthrax, because I was under the impression that Saint has no big touring plans anyway.
