Haven't had any experience with the Nexus switches but been reading some of the docs and i noticed -
"As Cisco's flagship switching platform, the Cisco Nexus 7000 Series is a modular switching system designed to deliver 10 Gigabit Ethernet and unified fabric in the data center."
Which is fine but according to the 6500 docs -
"With industry-leading services and performance, the Cisco Catalyst 6500 Series Switch is Cisco's flagship switching solution."
So i would be interested to hear from Cisco people or anyone else for that matter, which one is Cisco pushing as it's main switching platform in the data centre, campus environment. I know that each has it own capablilties ie. 6500 supports service modules etc.. but from a L2/L3 switching setup which actually is Cisco's "flagship" product.
I only ask because if it's going to be the Nexus i need to get a job again :-).

Each Business Unit will provide a different answer. At the moment, Nexus is winning over the 6500 in terms of throughput so its place would be at the core | distribution layer in a data center | campus environment while you can place the 6500 at the wan layer and many large companies also use them at the access layer.
Nexus provides the vDC concept where allows you to save in hardware cost but if you are pursuing a mature product, most people opt for the 6500.
Product variety is great and each offer an unique feature that forces you to choose one over the other.
The 6500 won't go away but learning Nexus OS isn't a hard transition.
