Fables, the Vertigo comic created by Bill Willingham and Mark Buckingham is already lined up for a new TV series. It has already spun off into books such as Cinderella, The Literals and Jack of Fables. It was recently advertised on BBC America. And publishers DC/Vertigo will be announcing a new spinoff ongoing title at this year's San Diego Comic Con.
In fact, with all the media interest and the upcoming Fables #100 extra sized, extra content extravaganza, San Diego may well be going a little Fables crazy this year.
A new Fables comic can only benefit from that.
UPDATE: Bill Willingham gets in touch to say "I'm sorry but no new Fables ongoing series will be announced at San Diego this year. There are no plans for a new Fables ongoing."
Thanks Bill. I notice you used the word "ongoing" twice there…
