From what I've heard the BCM will still be around, at least in the 200/400/50 packages for the time being. 1000 based hardware, the 3 slot chassis, won't be supported after 12/31/07 and can only be upgraded to release 4.0. Tne new SMB direction is SCS, Software Communications Server. Seems to be a Cisco Call Manager type of device, all software based running on a server.
