pretty much ruin the planned weekly mini-series that builds the team? Maybe it's misdirection.
Also, if Batman will be leading the Outsiders now, does that mean there will be a spot open in the Justice League? As much as I like the Big Three in the JLA, DC seems to have a one team membership limit and not having Nightwing on a team makes me think DC is freeing him up for death. He could go to the Titans, but what would be the point of two junior Batmen on one team, no matter how badass it would be?
