Mark Millar was offered to Write X-MEN 4 but Turned it Down?

So according to Mark Millar he was offered the opportunity to write X-Men 4 for Twentieth Century Fox, but that he turned down the offer because he's more interested in creating the next generation of superheroes. Who knows if what he's saying is true or not, there are some people who are very skeptical about it, but all we have to go off of is his word, and here is what he had to say on his blog. 

Fox just offered me X-Men 4… but I turned it down.

Why? I love the X-Men movies. The exec at Fox also seemed like a really smart guy who knows exactly what worked and didn’t work about the earlier trilogy. He has an abiding love for the comics and knew my work better than I did. I have no doubt he’s going to put together an amazing movie here because the people he’s talking about behind the camera are all friends and heroes of mine. He also offered me massive scope with the story and I have an idea I really like, something that takes the franchise in a really fresh direction.

But you know what?

I’m having so much fun creating my own characters and enjoying the control this gives you over the comic-books and the movies that handling an established franchise eems odd to me now. It’s tempting, SO tempting for a guy who’s been a fanboy as long as he can remember, but I need to stick to my guns. I want to create the NEXT generation of superheroes over the next few years and going back would, I think, be a mistake.

Vaughn is being offered everything you can imagine too in the wake of Kick-Ass, but we both agreed that keeping complete control is what made Kick-Ass such an amazing experience for both of us. Six big producers have now come forward for Nemesis (I’ve always said I’m holding off until April 17th before I let CAA take this out) and Vaughn and I already have our next movie planned out, based on a book I’m doing with Leinil Francis Yu in September.

But it’s still the friggin’ X-Men, guys. Have I gone mad? Was it nuts to turn this down?

I think the guy's gotta do what he feels is tight. If his heart wasn't in it then why do it? Millar has a ton of other projects being developed right now so it's not like he needs the extra work.

If this is true then it means Fox is moving forward with its plans to develop a X-Men 4 film.

What do you think about his decision?
