I really don't understand. With this people are like "well, it's the course of consoles etc." but when Microsoft was to shut down Live for the original Xbox..man that was panic and hell on the internet, people freaked out, and that was as I mentioned 5 years after 360's release.
Also regarding the PS2 network, even if only one game works now, it still is active. I also believe PS2 network isn't any system like live was, just a connection directly to a developer's server.
