Joshua Williamson speaks about Aquaman comic and why it does not have an ongoing. Seems he was offered the book and did not feel it was the right time even because of his plate being full. He hints that they have put the book on a break because they want to do right with it, and I assume that's probably because they need to balance creativity and financial return. He also relates that some writers(Bendis?) are interested and want to write Aquaman.
Its all about finding the right person who can write a book that brings back fans and keep them on board therefore also making it deliver in sales.
