Microsoft have stated that their goals are to beat the PS3 and keep it in 3rd place. That was one of the main reasons why I predicted that the Xbox 360 did outsell the PS3 last two quarters overall. Unlike SCE they are willing and able to sacrafice profit to achieve the long term mission. Their main aim is to get people using their online service "Live" and it does seem to be working. It seems to be extremely profitable and they have other ventures going online soon which could expand their marketability even further.
SCE is in a different position, I would say that any profit from SCE will likely be used to steady the rocked ship which is the Sony corporate empire. They will not dole out price-cuts like candy, only when circumstances allow it and I do not forsee them dipping into heavily unprofitable territory in hardware for the rest of the generation.
You see, long term Microsoft is in a more profitable position with the Xbox 360 and Live than Sony is with Blu Ray and the PS3. The difference between the two is that Live is incredibly profitable, but didn't cost them much at all to implement. They also get the majority of the profit to keep for themselves whilst Blu Ray profits have to be shared amongst dozens of companies (Microsoft included). Microsoft can use profits from Xbox Live to subsidise the hardware, whereas Sony up to this point cannot do the same.
Tease.
