AFAIK you cannot expect 40G for 7600.
Are there any (public) reasons given for not offering 40G for 7600?
My assumption is the following:
- sup720/rsp720 series backplane connectivity capacity is 40Gbps
- there is no known plan from Cisco to have bigger capacity supervisor
for 76xx.
- Probably not economical to develop 1 port 40GE card
If i remember right, a 4x40G card (oversubscribed) is under
consideration for the 6500/Sup2T.
Also, Nexus will get 6x40G and 2x100G cards, non-oversubscribed.

- If you need router like capabilities Cisco pushes you to go for
ASR9K - Comparing pricewise 76xx with ES cards and ASR9K with low
queue cards there is not much difference.
