Wow, I think I heard that Microsoft already has put that idea in their Xbox 360. Score one for Sony relatively taking ideas from another company. Anyway, Phil Harrison (head of PS3 gaming stuff), stated in an interview that “we have a hard drive, we have a commerce engine, it doesn’t take a rocket scientist to figure out we will have that on the network very shortly.”
Saying basically that it will have movies. And then he hints later that it will have IPTV support.
