Glad we're at least getting some confirmation on where things are headed - and at least in this case they are actually confirming that yes, Bruce is Batman/Dick is Nightwing/Damian is Robin/Barb is Batgirl. There sure is a mess of books in the Bat-universe coming up though. I did see that Grant Morrison's Batman Inc. is coming back in January of 2012, so that's good news that it is at least coming up.
Like Jeff, I guess I'm glad Dick Grayson is Nightwing instead of Jason Todd, but otherwise I'm not sure what to think of it. Other than Spidey/Peter Parker (and possibly Bruce/Bats) Dick Grayson has always been one of my favorite characters, and while I really like the Nightwing persona and everything, he just doesn't seem real relevant or important to the DCU (at least in the past). I mean, I can understand not reverting him to Robin (that may have been too much) and also, to some extent, returning Bruce to the only "Batman" (since part of the point of their reboot is to make things easier to understand for new readers) - but I feel like Dick was much more integral to the DCU in both of those roles than as Nightwing. I just hope that they keep him more involved with the rest of the DCU, and not just let him fade away a bit again. To me, he is sort of one of the pillars of the original DCU alongside the "Big 7" and a few others.
As mentioned, still wondering where Tim Drake fits into things - unless that announcement is yet to come. Looks like there are potentially some nice books coming up, but speaking as someone who most of the time was reading the majority of the Bat-related titles, I don't think I'll be able to do that anymore. A lot of stuff on the way. I will sort of miss the Dick Grayson/Damian Wayne B & R though, good stuff.
