I've always scratched my head over MS in ERP -- the market space hasn't grown at rates that MS needed for a decade at least. CRM gets sold mainly into MS shops, where IT really likes the pure MS stack it requires. Its win rate outside of that target is far lower. Commonly spouted rationales by analysts have been that MS did CRM only to sell its stack. As the CRM market consolidates to sfdc + the rest, and with more large firms getting comfortable with sfdc (which uses NO MS stack) it is hard to see why MS keeps the whole ERP-CRM business.
I think MS is coming to terms with the fact that it will not be a big business apps supplier. I won't be surprised if MS simply spins the whole Dynamics operation out as a separate company. But then i thought that would happen a few years ago, too....
