I remember after Crisis Of Infinite Earths that two creators/contributors to the old DC Multiverse, Gardner Fox and E. Nelson Bridwell, died soon after and DC didn't care enough to send representation to the latter's funeral.
I guess the regime behind Marvel will be as callous to their remaining founding fathers/key contributors Stan Lee, Steve Ditko, John Romita, Sr. and Roy Thomas. Why not, since they are destroying their legacy?
It makes me wonder why Marvel bothered settling with the Kirby estate since they are cancelling FF/destroying the rest of Kirby's co-legacy.
I don't think the legacy aspect will end. That doesn't mean the same thing as ending one era to start a new one. For my money that Marvel style ended well over a decade ago. I have said Marvel should start over because the old style Marvel which so many of us love is gone and the medium has a completely different way of looking at what comics are for and how they should be used. Continuity and characterization were a bedrock that under penned that style. After over fifty years maybe it is time to do what Stan,Jack, and all those that came into the fold after did and break the mold and try to do something fresh. We love the era past but I think allowing it to become history will not tarnish the legacy. Indeed in these days people will have access to those decades material far easier and I think it will always remain held in high esteem. I have to say though whether current Marvel can pull it off or even really stick to such a company wide idea is dubious. As others have pointed out it will surely end up as at most a partial reboot and we know how well that works from D.Cs. problems. It will probably be used to bring the comics more inline with the movies. Honestly it sounds like they are doing Ultimate Universe all over again as opposed to really becoming a new 616. Battleworld will sell huge so Marvel will have a lot of momentum heading into the new M.U. and I guess it is a matter of wait and see.
