You thought PerformancePoint Server is dead? It is not!
Microsoft announced a new Accelerator-component on their partner website; The "Financial Planning Accelerator". This component is derived from the source code and project files of the Planning Module of PerformancePoint server and is available on a non-cost, individual license.
Microsoft Partners can get and modify the source code like it were open source. But in fact it isn't, because PPS Client Access Licenses are needed to distribute the code to the end users.
You can find more information about the Financial Planning Accelerator on Microsoft's Partner Website.
