Doomsday. We all wanna see it, though I don't know how you'll top the Zod fight for sheer destructive chaos, but it would be fun to see you try.
In the next film Batman begins to lose sight of his goal, Night wing will try to stop the new Batman as his methods become much more akin to the foe he's previously try defend the city from. He fails.
The darkest of knights resorts to dirty, underhand, and downright ungentlemanly tactics, that put him on an even keel with Superman. The most prevalent being the rare 'Kriptonite' that sits in the labs of Wayne Enterprises.

Then the missing presumed dead Nightwing returns with an old acquaintance. Bruce Wayne, (just imagine the hype when they convince Bale to return to the role in 10 years time) back in his batsuit after 10 years away, brings his decades of training and expertise back to Gotham City. Here we get to see two batmen, one suped up 'bad' batman, and one 'classic' meditative warrior go at each other through the crumbling ruins of Gotham.
