I'd wish they'd realize there are other characters besides Batman to make a cartoon out of. Think of all the superheroes with plenty of great material to work with.
Umm... Batman: The Brave and the Bold
is a series that teams Batman up with different DC superheroes every week
. They've featured dozens of characters from the famous to the obscure -- even the likes of Kamandi, Detective Chimp, and Bwana Beast have had recurring roles. And Young Justice
, which airs right after BB&B, features pretty much the entire DC Universe, with Batman in a supporting role.
They keep headlining cartoons with Batman because that's who the viewing audience wants to see -- because shows starring Batman have been perennially more successful than shows he wasn't in. But they're using that interest in Batman as a means to expose that audience to the whole panoply of DC characters. Which is an entirely sensible way of going about it.
Is this the same Katana who is one of the nuDCU Birds of Prey (well it probably won't be that version of the character, but you know what I mean)?
Yes, apparently so.
Shame there's never been a Nolan-inspired Batman cartoon (softened a bit for the kiddies, obviously).
There has been. The Batman: Gotham Knight
direct-to-DVD feature was a series of anime shorts set in the Nolanverse between Batman Begins
and The Dark Knight
(although it had a couple of continuity discrepancies with TDK). And it wasn't softened for the kiddies; it was a pretty hard PG-13.
