significantly less than XBOX Live..thats pretty much a fact
Sonys decision to make PSN free was simply a means to an end = profit
Just like microsoft & 90% of profit driven companies, there is no such thing as a charitable, consumer caring mega firms in the world, their main intentions/motives is profit maximisation The differences between them however is that they all have different means to maximise profit.
-One of Sonys model for profit for online services = 'make psn free' = add value = profit
-Microsoft's model for profit = 'enhance LIVE' = subscription = profit
It is clear which model has achieve higher profit, which is why I think Sony's subscription service is imminent
