N7K is optimized for 10G today & will scale to 40/100G in future. 
6500 is 1G/10G optimized today and w/80G per slot it could clearly 
support 40G as well. Does a 1-port 100G module w/80G capacity make 
sense? Possibly, it's TBD AFAIK.

WRT your specific application, if the shoe fits, wear it. That said, 
6500 is not going anywhere any time soon, it has and will continue to 
play many network roles for the forseeable future.
