In an interview with Kurt Amacker for Mania, Alan Moore discussed in detail his feelings towards Marvel's purchase of the Marvelman character and the chance of ever seeing his own version of the character in print again. In a nutshell: He's fine with it all as long as his name is kept off the credits and the character's original creator, Mick Anglo, gets to keep all the money:

After being initially informed by Neil’s lawyer, I had to think about it for a couple of days. I decided that while I’m very happy for this book to get published—because that means money will finally go to Marvelman’s creator, Mick Anglo, and to his wife. Mick is very, very old, and his wife, I believe, is suffering from Alzheimer’s. The actual Marvelman story is such a grim and ugly one that I would probably rather that the work was published without my name on it, and that all of the money went to Mick. The decision about my name was largely based upon my history with Marvel—my desire to really have nothing to do with them, and my increasing desire to have nothing to do with the American comics industry. I mean, they’re probably are enough books out there with my name on them to keep the comics industry afloat for a little bit longer. I left a message to that effect with Neil. I’ve since heard back from the lawyer upon another issue, and he said that he was certain that would be the case—that Marvel would accede to my request. That looks like the way it will be emerging. And, Neil will be able to finish his Marvelman story because he has a completely different relationship with Marvel than I have with them—or rather, don’t have. The main thing is that I will feel happy to know that Mick Anglo is finally getting the recompense he so richly deserves. And, I will have distanced myself from a lot of the deceit and ugliness that surrounded the relaunching of Marvelman as a character.

Moore also has a few nasty words for former Warrior editor Dez Skinn and Eclipse Comics, and goes into great detail about how he came up with his own unique take on the character. Go read the whole thing.
