Thanks Neno - I missed the release earlier this week as I'm strictly mobile while on vacation. :)
I was embargoed from discussing much as I had non-public information. But as the release notes mention, SSL decryption and a host of other features are now available in FirePOWER Management Center 6.0.
"Cisco’s next-generation firewall (NGFW), Cisco ASA with FirePOWER Services, now has the ability to locally manage SSL communications and decrypt the traffic through ASDM before performing attack, application, and malware detection against it. This is the same capability we introduced in Version 5.4 for Cisco’s Firepower next-generation IPS (NGIPS) appliances. SSL decryption can be deployed in both passive and inline modes, and supports HTTPS and StartTLS-based applications (e.g., SMTPS, POP3S, FTPS, IMAPS, TelnetS). Decryption policies can be configured to exert granular control over encrypted traffic logging and handling, such as limiting decryption based on URL categories to enforce privacy concerns. It also provides the ability to block self-signed encrypted traffic, or on SSL version, specific Cipher Suites, and/or unapproved mobile devices."
