Microsoft Identity Manager 2016, successor of FIM 2010 is now available on MSDN / Volume Licensing sites. It is the "GA" version.
There is also a new site about MIM:
Microsoft Identity Manager at microsoft.com sites.
On-premises identity and access management:
- Synchronize identities between directories, databases and applications
- Self-service password, group and certificate management
- Increase admin security with policies, privileged access and roles
- Thwart identity theft with Microsoft Identity Manager (MIM)
Note that there is "Try now" button on the site, but it is currently redirected to /evalcenter/evaluate-microsoft-advanced-threat-analytics
