Well since I work at a comic shop and the Diamond Catalog for December comics which will ship in Feb 2009 is out. The following has a lot of spoilers so I am placing a spoiler box around the test below in case you do not want to know what's coming next February.
The latest issue of Batman (#681 key issue to what's coming) came out this Wednesday and it is the conclusion of Batman: Rest In Peace. And yes Bruce Wayne is dead. Gone. Finished. It's is not made plain at the end who will take his place, Dick Grayson/Nightwing or Tim Drake/Robin. Nightwing is the one pictured at the end. But the December Previews from Diamond is soliciting comics for Feb 2009 and the following has been released.
The Nightwing and Robin issues in Feb 2009 are the final issues of those comics. They are dropping hints only saying that the final issue does not mean the end of Nightwing/Robin but the beginning of something new.
Batman and Detective Comics will continue. The cover of Batman #686 shows a funeral like procession but upon closer examination, it is all his main villians and they are all walking into a Gotham City Building. They are looking at something on the ground as they walk. Cats. It is titled "Whatever Happened to the Capped Crusader?" by Neil Gaimen and art by Andy Kubert and is part 1 (Part 2 will be out the same month in Detective Comics #853) The write up for these comics indicate that Neil Gaimen will leave no stone unturned when he takes up that task of telling Bruce Wayne's life, friendships, connections and takes us to an exiting and unexpected climax. The cover illustrations are very onimus looking.
The final issue of Nightwing shows him jumping through the air surrounded by bats. It says the Mantle of the Bat must now be passes and Dick Grayson as Robin fought beside the Batman but who the Mantle passes too will be decided by Bruce Wayne's last wishes. Will this be the last time we will see Nightwing?
The final issue of Robin has a very angry, distraught, upset, kneeling Robin with a ghost-like image of Batman behind him. He is on a rooftop in an incredible picture. It says; is Tim Drake ready to take on the mantle of Batman and defend Gotham City". "Guest Staring Jason Todd and Lady Siva this is not the end of Robin but a new beginning".
Nothing is mentioned in any of the Titans books about Robin leaving, so far.
As a side note the following DC Comics will also have their final issues this February but none are because of Batman. Blue Beetle and Birds of Prey.
