AAM iSession replacement?

Hi, I am aware per this that the AAM product suite is going away, and is not even available on current hardware models. I am currently using iSessions to create optimized tunnels for some TCP traffic between sites, which is then secured with SSL profiles. In particular the deduplication and compression is what we mainly take advantage of. My question is, is this functionality going to eventually ship in the eventual BigIP product? Or is iSession/Dedup/Compression simply going away?

Thanks, Bryan
