Yea, that is what I've discovered based on my research in the past few days. 
The Sup720/3BXL costs a heck of a lot more than the Sup2/MSFC2, so I would like 
to avoid that route if possible.  It makes the decision between a 6509 vs 
72xxVXR/NPE-G2 vs Juniper for core routing a lot harder.

Power and space won't be a problem for us since we're putting this in our own 
facility.
