A lot of this also depends on what else is or could be driving your 
decision, beyond needing 10G ports.

For example, how aggressively will you be rolling out IPv6?  Sup720 can 
handle IPv6 well enough, for the most part, but the jury is still out on 
how well the 720 could stand up to either a misconfigured/malfunctioning 
host blasting out neighbor solicitations, or a compromised machine doing 
the same, before tipping over.  There are NDP table management features 
that have been pack-ported to 12.2SXI, but I haven't had a chance to test 
how well they work.  There are also concerns about how well the 720 
handles things like multicast IPv6 traffic, and IPv6 CoPP.

Also, if your long-term plan includes anything above 10G, you need to look 
beyond the 6500 platform.

If having vendor-supported gear in your production network is a must, it's 
time to consider the Sup2T or moving to the Nexus platform.  The Sup720 
has served us extremely well for the past 8-ish years, but it's starting
to get a bit long in the tooth, as is the 6500 platform itself.  It's 
stable, proven platform, and it's on Cisco's product roadmap for probably 
another 5 years, but the number of 10G ports, and the amount of per-slot 
bandwidth is what will ultimately determine its usable lifetime for many 
customers.

Much like the 7200 VXR platform, the Cat6500 will likely live on for a 
long time, because of its versatility, but performance requirements will 
ultimately win the business-case arguments that will drive many customers' 
strategic decisions and capital expenditures.  That will ultimately drive 
when Cisco decides to phase out the 6500 platform.

Currently we have 2 6509-NEB-A's in core, and we are trying to weigh options on either upgrading sup's line cards to go 10gbit or looking at Nexus gear.  Obviously there is a little bit of dollar pain when even thinking nexus so I am trying to investigate a lower dollar thought.  We have to stay on something current so the next thing that came up is EOL/EOS on the 6509-NEB-A. Has anyone heard anything on when this might hit for the 6509-NEB-A platform?  We know our sup's go EOL in about a month, but I'm not finding anything on the 6509-NEB-A specifically.
