Has anyone heard any news with the 802.11ac module? Is this going to be an add on module or a completely different box. I have been contemplating purchasing the new Mark VII, but I need the 802.11ac requirement as most of the networks I work with are in the 5GHz band and only use the 2.4GHz for LBS systems. I thought about getting the Mark VII to start playing with the new setup and C2 cloud etc, but don't want to throw money at it if the 5GHz module is going to be a completely different form factor. Anyone have any thoughts?
