Batman #675 is the bridge to RIP from...everything that's come before.
When Morrison said everything he's done so far was leading up to this, he wasn't kidding. This issue has Jezebel, Robin, Nightwing, Talia, Merlyn, Damian, and a Nine-Eyed Man. There's fallout from Nanda Parbat, the previous arc with the Robin Dies at Dawn threads, and the palpable presence of an unseen foe who may or may not be the Black Glove -- and we close with a surprisingly violent, pre-52-style Bruce. The only pieces of Morrison's entire run that are missing are the Joker and Bat-Mite (and of course the latter seems to have just been a hallucination induced by blood loss). (And, in another nod to Golden and Silver Age continuity, Alfred's last name is apparently back to "Beagle", not "Pennyworth".)
For all that I think the title is standard comic book marketing absurdity, I am convinced that Batman: RIP is going to be good. All the dominoes are in place, and I'm really looking forward to seeing Grant knock them over.
