This is an interesting development if true. Rich doesn't state a source for his statement regarding Diggle's supposed departure.
Diggle and Daniel obviously have issues in the can already so perhaps this will be announced as a mini-run or something like that before a new creative team is announced...of course if this even ends up being true.
Remember, Rich was the one who reported that Diggle would replace Morrison in the first place. It's probably accurate since a lot of BC
's stuff come from the Con/Pub scene across the Atlantic.
Likely Daniel pushing to get himself named the writer on Action. This is the third time that DC has bent over backwards to accommodate him.
