Renumbering has never really bothered me. I mean if a good story is told at #1 or #600, it's still a good story and that's what mainly matters to me. But then again, continuity doesn't especially interest me, so I'm weird. I like the past stories, but their existence in canon (or lack there of) doesn't make me like or dislike the past or current stories anymore because if it's a good story, that trumps everything. And if I can't get over its place in continuity, then I'm worrying about the wrong thing and the story's failed.
I will say that 90% of creative decisions from comic book companies leave me scratching my head. But I must commend them for being creative. Some of these characters have been around for 50+ even 60+ years, it makes sense that they start to grow stale. So I do commend the editors for allowing Bruce Wayne and Steve Rogers to be killed for a while, for Planet Hulk to happen. Utopia, Schism, Final Crisis, everything going on in GL (minus the retread of Hal Jordan, because that is regressive). While I may not enjoy all the resulting stories or the core of the decisions, I commend them for trying. It would be super easy to continue to tell stories of Cyclops, Wolverine, Jean, Beast, Rogue, Gambit, Storm, Nightcrawler, Colossus, Archangel, Iceman and Kitty in the mansion with a very friendly Professor X or for Bruce Wayne to constantly be suiting up and fighting average gangsters.
Anywho, that said with the Hulk, Jason Aaron is a fantastic writer. However, by my counts he'll have 4 books in November. Wolverine and the X-Men, Wolverine (solo), Hulk and his creator owned work Scalped. Unless he has one of those written far in advance, I'm worried that the work load will start to hurt his work.
