I attended the ASUG today, and I did not feel the BPC is better than IP for a SAP customer.I do not know whether BPC have characteristic relationship, retraction etc, but just from the layout, IP could give you the same thing.
For the consolidation part, I think it takes consolidation too simple, maybe it is just OK for management consolidation but not for legal consolidation. It does not say whether BPC support multiple level consolidation but it looks not.
The only better thing I see is the user interface. It is interesting that SAP suggest us to use BPC for our new project:)
