I can't answer your question as I haven't really followed comics in some time.

But damn, virtually everything you mentioned seems like a TERRIBLE idea. Those were all things I absolutely loved about Marvel:

- long histories, back stories, continuities

- crossovers between comics and characters (though I admit it was irritating when a 10-part story took place in 10 different titles)

- secret IDs and the pressure of maintaining them usually made for good plot elements


The lack of crossovers and each hero existing in his own New York seems like the worst idea of the bunch by far.

Wow. That definitely doesn't sound like the Marvel I always loved.
