Last year Sony made mention of a "Home" service that would allow users to fellowship with one another. Originally this "Home" service was going to launch at the end of last year, but was postponed until early this year.
Bringing up the rear behind the XBOX 360 and ultimately the Nintendo Wii, I'm not sure how many more delays PS3 customers can afford. Sony needs to get the ball rolling if they want a bigger piece of the gaming sales pie.
