Geez, what a missed opportunity. I mean, c'mon, if Dick becomes Batman, and Damian becomes Robin, then there's NOBODY filling the Nightwing costume! It's obvious Tim needs to take up that identity and become the new Nightwing!
Yes, I know about Chris Kent, but as far as I'm concerned, Nightwing stopped being a Kryptonian hero a long time ago. He's part of the Bat-Clan now.
