Yes, I remember Bendis saying that, but I thought that was more about concepts, rather than him writing Batman Universe to be in continuity with the rest of his work. Similar to how him writing J. Jonah Jameson would have similar concepts, but not be the same character, as Perry White. (Brought to mind by the way Perry in King's Superman seems similar to JJJ )
I'm hopeful that Gleason and Bendis's new book will be awesome! I really like Gleason's art.
I do think King loves Superman. I think we'll have to wait and see if he's really good at him.
