What is the difference between cisco 2921 sec k9 router and cisco 2921 ax/k9 router

[Mark Malone]

Cisco^® Application Experience (AX) routers revolutionize the delivery of application-aware services in the branch office and WAN, with comprehensive solutions for application visibility, control, and optimization to enable customers to successfully deploy, monitor, and troubleshoot their applications from anywhere.

Well as I understand it, basically the AX/K9 portfolio is a little more "app oriented", they are bundled with SEC and APP Licenses and WAAS/vWAAS, there's also an option to include Akamai Connect licenses for IWAN.
