This is just a little blog posting to announce that the first fix for SQL Server 2012 came out last week during Easter Break.
This KB with the number 2685308 is just for SSAS.

In the RTM version, SSAS is limited to the 20 first cores. With this fix, there is no limitation and you have all cores available for your OLAP solution.
You can find more detailed information here.
