You know, it's also possible that our regulars may THINK that Robin dies, but in fact something happens that separates him from the rest, and in such as way as to leave the impression that he's dead. Go back to the End of Season 2 and Beginning of Season 3. Everyone thought that Neal had died  after being shot by Tamara and then falling through a portal.

That's a common enought storyline that it seems a little lazy, and I'm not sure they will go that direction, but I'm just trowing this out there as another possibility. Which means that this could be a Robin Centric, with Robin "dying"/disappearing at the end.
