Ryan has a good post about how huge playstation is with 650M downloads of data before Facebook connect launches.

There were of course a lot of articles about the sale of playfish to ea which makes me for one really excited about the idea of getting all those great ea games (e.g. Risk http://hasbro.ea.com/game.action?game=risk) onto my favorite social networks.
And finally xbox announced 2MM users connecting via Facebook already in just days.
People want to play games with their friends (I for one love farmville and would really like to see Risk on the Facebook platform and would pay to play).
