I'm not sure what you are really asking? Are there new features we are expecting in AOS now that it is part of HP?
AOS is a mature system which as been deployed for years. ArubaOS will be brining support for Wave2 devices in coming versions, but i dont see anything which would be a show stopper today to deploying Wave 1 802.11ac devices.
What are you concerns right now? Things are Aruba should not be changing too drastically after the HP takeover, at least from a technology perspective.
