The thing I want to know is how much are they going to "reboot" exactly? Some people called Casino Royale a reboot, yet others treat it as a retelling of Bond's early days.
In some ways, X-men First Class is a reboot, yet it's still loosely connected to the continuity of X1 and X2.
Personally, I hope that they treat the Batman series like the Bond series after these first three films. If Nolan doesn't kill off Batman or do something radical that would demand a complete reboot (Alfred or Gordon dying, Batman being revealed to be Bruce Wayne etc). Then I hope they just start making movies set when Batman's already established. Leave the origin stuff alone and move on to other stories.
Like I said, a loose Bond-like continuity. That way, we could also have a wide variety of styles. The Bond comparison really works best here, because when you think about it, he's about the only other cinema character besides Batman who can have such varying styles of film. Batman should be the same way.
So just because they're "rebooting" doesn't necessarily mean Nolan will be doing anything to force their hand. It all really depends on exactly what they mean by a "reboot."
