I'm not surprised honestly, Bendis is NOT a good fit for the GotG. He's been doing nothing but having guest stars and meaningless crossovers with them, and they feel totally out of character all the time.
Sorry, end rant.
This is the exact reason I dropped this book. This Bendis run is the first time I followed this incarnation of the Guardians and I left at at issue 13. I felt at that point like I didn't know the characters at all much, and it read more like a "Guardians Team Up" book. I like Bendis normally.
This is a win for Marvel on all fronts. They'll get the announcement out to an entirely new audience, and the anti-diversity whiners for whom this sets off alarm bells will help ensure the existing audience is buzzing about it one way or the other too.
