Microsoft Product Lifecycle Search for FIM 2010 R2:
There is more info on Microsoft.com/lifecycle which is relevant. From this site (first section in FAQ):
“Microsoft will offer a minimum of 10 years of support for Business, Developer, and Desktop Operating System (consumer or business) Software Products. Mainstream Support for Business, Developer, and Desktop Operating Systems will be provided for 5 years or for 2 years after the successor product (N+1) is released, whichever is longer.
Microsoft will also provide Extended Support for the 5 years following Mainstream support or for 2 years after the second successor product (N+2) is released, whichever is longer. Finally, most Business, Developer, and Desktop Operating System Software products will receive at least 10 years of online self-help support.”
R2 is a minor release and not a vNext product. FIM2010 is the main vNext product and it defines the lifecycle. R2 is a minor release and it will inherit the lifecycle from the main release.
You will find the same policy for other R2 releases, such as Windows Server 2012R2.
At the time MIM vNext is released, FIM2010 will automatically get its support extended by 2 years to summer 2017. That should give customers enough time to upgrade from FIM to MIM even if they start with FIM today. The support statement is on the Lifecycle page is likely to be updated at the moment of RTM of vNext.
And, as announced at TechEd, MIM RTM scheduled for mid-2015.
