I think that DC is far more guilty of this sort of behavior than Marvel is. For all my gripes about the way Brian Bendis writes dialogue, his love for characters like Luke Cage is genuine, but he hasn't tried to force them back to their roots. Rather than reverting Luke back to his Power Man days, Bendis took the character in a brand new direction, having him join the Avengers, marry
Jessica Jones and be a bad-a$$ character, while doing something new. The same goes for Dan Slott on "Amazing Spider-Man", where he took sad-sack Peter Parker to his lowest point (fired as his job as photographer for Mayor J. Jonah Jameson) and turned him into a research scientist at a start-up company, where Peter turned the inventions he used to fight crime into medical devices, consumer electronics and other interesting products. Then Doc Ock stole Peter's life. Bet ya didn't see that coming, huh?
Meanwhile, at DC, Geoff Johns is single-handedly responsible for sidelining characters like Kyle Rayner and Wally West, legacy heroes who earned the affection of fans during the 1990's, while shoehorning the heroes they replaced back into continuity. He rewrote Superboy's origin, forcing his head-canon about who donated Connor's human DNA, changing the donor from Project Cadmus' crooked director to Lex Luthor (who was masquerading as Lex Luthor Jr. at the time Superboy was created by Project Cadmus, and took steps to recover Superman's body from Cadmus to keep him from being cloned!). Geoff Johns has never met a piece of post-Crisis continuty he didn't want reverted back to the Bronze Age status quo, and now he's become Dan DiDio's hitman when it comes to reboots. If the nu52 doesn't increase sales, DiDio will order another reboot, and another and another.
Meanwhile, at the House of Ideas, they have good ideas ("Superior Spider-Man") and bad ideas ("Avengers Arena"), but they aren't rehashing every single idea from the last fifty-odd years. Marvel is still capable of entertaining me; I can no longer say the same for DC.
As for Gygaxian!Belkar and Gygaxian!V, won't that be awkward, now that V's gender has changed, and Belkar's childhood traumas have changed, given him different fetishes?
