The main focus of CCSA R80 was the management side of things, and since R80.10 management has not changed a huge amount between R80 and R80.10 (certainly not nearly as much as R77.30 -> R80) the CCSA R80.10 course is not that much different from CCSA R80. The major additions in CCSA R80.10 are the addition of a HTTPS Inspection lab and a few new lab tidbits with inline policy layers and Content Awareness. I don't expect the exam to change much between CCSA R80 and CCSA R80.10, so I doubt if you obtain CCSA R80 certification that you'll be required to get CCSA R80.10 to then be able obtain CCSE R80.10.
The CCSE R80.10 course however is substantially different than CCSE R77.30, and there was never a R80 version of CCSE.
