In this interview with Peter Tomasi, http://www.comicbookresources.com/?page=article&id=43937 he says in regards to Batman & Robin, from #19 on, "The title of the series for the next several issues will change, the first being "Batman And Red Robin," the second being "Batman And Red Hood."
He also states that "There are five stages of grief, and we intend to explore it in a very visceral way."
This makes me think that after Red Robin and Red Hood, there might be three more "Batman And..." issues, one for each stage of grief. Or it could be that they do more.
What I'm wondering is, who would everyone like to see in these team up issues?
