Any upcoming gateways that aren't Fusion

Loving the look of the new Fusion gateways, but being honest, I'm happy with my software controller. I don't really want to be locked into something where potentially the controller part is going to eventually end up mad slow (looking at you, OC200), whilst still being happy with 1Gb+ DPI and 2.5GB LAN ports on the gateway part.

Anyone on the inside know if there will be a replacement to the ER605, for example, that I can just provision into my network and not have to replace the controller? Considering the upgrade to a ER707-M2, but a full suite of 2.5GB would be ideal and save me an additional switch.
