[c-nsp] 12.SR vs 12.2SX train

[Hank Nussbacher]

I have reviewed:
http://www.cisco.com/en/US/products/hw/routers/ps368/prod_bulletin0900aecd805df25d.html
http://www.cisco.com/en/US/products/hw/switches/ps708/prod_bulletin0900aecd80628341.html
but am looking for a Cisco page that would be a line by line comparison of 
the two versions, where I can see hardware features (i.e. RSP720, CSG-2, 
Baldur, etc.) and software features (OSPF graceful restart, BFD VRF, VSS, 
etc.) and which train will support which feature and when they plan to 
support it or not at all.

I have seen various PDFs that have bits and pieces of this puzzle (6500 & 
7600 roadmaps), but no single document that compares one to the other on a 
line by line basis.

Any help?

Thanks,
Hank
