Don't see Exchange 2013 Provision on FIM 2010 R2 SP1

Hi FIM Engineer,

Now, I install FIM2010 R2 SP1 (build 4.1.3114.0) on Exchange 2010 forest and I will go to Exchange 2013 in the future. But why I don't see Exchange 2013 provision for select in Configure Extension Menu? (I can see only "No provision", "Exchange 2007" and "Exchange 2010")

I download SP1 to install from http://support.microsoft.com/kb/2772429

Regards,

Thanachart R.
