I believe that the comment is correct, but there are some points that should be better explained.
Cisco will launch devices with chips already used by Arista since 2012.
All these benefits are touting that are already used by Arista since 2012.
All services that are launching is possible only in the Nexus 9000 line, which is very similar lines of Arista. And its features are already ok.
All customers who have invested in the Nexus 7000 line will not enjoy his legacy for new services SDN, CLOUD, VXLAN and new features.
Sorry my sincerity
