I don't really see the point of renumbering unless you actually start the continuity over. I know they do it as a way to attract new readers, but I really think if people are interested enough in the comics to read them, they'll probably read them whether it's number 1 or 701. But I guess that could just be me.
Personally, I've pretty much given up on these comics. You are bombarded with series after series, with crossovers, and the same characters in multiple series (which sometimes reference each other)... it's just frustrating for the reader and too damn expensive to stay on top of it all.
Couldn't they limit themselves to one series/issue per week with more pages per issue (quality instead of quantity)?
There are 15 NOW-issues in for 10 series due out in November. That's overkill.
