The last time they did a show set in Gotham without Batman, it didn't last very long. We'll never get a tv series with Batman actually in it, so long as the suits are scared nobody will pay to see the big screen versions in the pipeline.

That's one reason I like Person of Interest. it's as close as we are ever likely to get to a real Batman series. It's very much in the same spirit and our characters face the same types of problems Batman does so if you close your eyes and squint it can pass for a Batman tv series.
