will we be able to delegate reverse dns for our ip pools sometime in the future to a server of our choosing?

I don't know. However --

You know that you can set rDNS for your pool IPs on the rDNS page, just like all your other IPs? Just enter the hostname in the box.

I too would like to see this functionality, or at least an API call to invoke the forward/reverse matchup. Logging into the manager and doing this through the UI is ok for one or two hosts, but when you have a dozen or so, this really doesn't scale.

I would also point out that there is no way to remove an rDNS record once it has been created.
