Most games that are F2P come with premium content, as well as a steady subscription to get all that premium content for... well "free" isn't a better word, but discounted from the total cost.

Sony doesn't have any of that money coming in. They just have their little store like the XBLA, but even the XBLA is heavily supported with a host of games that aren't available for the PS3

Microsoft made more money with over a million people paying $5 a month (it really is more GOLD members, but this is an example) They easily can get a few million a month more than the PS3 through LIVE. That money goes to staff wages, servers, and other costs, but the excess.... that goes for promotional deals like the monthly exclusives.

Especially since Games-On-Demand like the Steam model will be more and more popular as well, Microsoft has a business leading system going into the new generation of videogames.

Expect Microsoft to dominate these deals until Sony decided to actually charge for subscriptions.
