Never underestimate Microsoft's ability to throw money at something until it sticks. They shoved billions of dollars into their Xbox division before it started to show a profit. If they're really committed to mobile phones, they shouldn't have any issues with spending a few billion to bootstrap things.
Their biggest problem right now is that there's no compelling reason why anyone should buy a WP7 phone as opposed to anything else. There are still plenty of consumers who don't own smart phones, and plenty who do who don't have a huge preference to the phone that they use. Microsoft needs to provide a compelling reason for all of those consumers to pick WP7.
