What I'd really like to see is maybe a series that uses Nolans trilogy maybe as a backbone. The origins already good, and done, why mess with that? As someone earlier has already mentioned a James Bond type of continuity, something that intrigues me alot. Different directors with different takes, but retaining the same tones as the previous ones.
And if they find a cool way to introduce Robin, that would be cool, allthough I like my Batman as a loner. IMHO introducing Robin would have made a really cool tv-series(HBO), one season on how he came to be Robin.
But thats just me
