personally in time I think Damian will come back to life, I mean his mother has a Lazurus pit and it is a simple fix. but what I find interesting is that Harper Row is going to return in Batman #18. It is my guess that she will become the new robin eventually. If you read the news Tim and Jason are going to be Batman's partner in the next few Batman and Robins and I think slowly but surely Harper will become the next robin.
I also think that Damian should abandon the Robin mantle and become Flamebird and partner with Dick Grayson. Dicks partnership with Damian, in my mind, was simply just better and more enjoyable then anything Bruce and Damian did. Also if you look at Nightwing 17 and Batman inc 8 they say they should partner up together more often. I think that is what is going to happen Nightwing and Flamebird
