I'd seen some conflicting info though and wasn't entirely sure. Cisco also
doesn't seem to list that for all the supervisors, although on the '720s
they are more specific.

Sounds like it's good for about one year or so then :-(

This is unfortunate since we need the space for routes but don't have
needs for anywhere near the 720Gb/s switching performance of the Sup720's.
