Introduced more than one year ago with the MCSA level, where completed with the MTA certifications that are the entry level, especially for people that don’t know already the Microsoft technologies. I’ve reach the MCSE: Private Cloud certification on September 2012, but using some “short” path (time limited), so it wasn’t really a complete example of what are new MCSE certifications.
