>Samsung could be a good buyer for Nokia. It could switch over the supply of Nokia's internal components to Samsung thereby creating synergy. Samsung could swap out Symbian with Bada on lower end phones and (depending on the Microsoft contract) Android on the high end.

I don't think Samsung would stop the Win7 phone production, or convert existing phones to Android from Win7. They already have a few Win7 phone models that reviewed pretty well. This would remove a potential competitor for those phones, as well as put them in a better position to deal with MS about the OS itself with Nokia's technology and supply chain.
