In some ways it makes more sense than MS buying them. MS is primarily a software company, Sony is primarily a hardware company. Sony makes componentry that is used in devices manufactured by other companies (sensors for iPhones for instance). AFAIK MS does not supply hardware components to 3rd party device manufacturers.
Sony is therefore better suited to become a chipset manufacturer and supplier than MS is.
Problem is, Sony really does not need to acquire a loss-making venture and try to turn it into a profitable division of the company. If they were in a better financial position themselves then this would not be such a left-field suggestion.
