Sony just announced at E3 that Playstation Network users now have the ability to rent and purchase moves and TV shows. Like, immediately -- the service is getting flipped on tonight. It's not just Sony content, either: Fox, MGM, Lions Gate, Warner, Disney, Paramount, Turner, and something called Funimation are signed up from the get-go. Video will be available in both SD and HD, and TV pricing starts at $1.99. Movie purchases will run $9.99 - $14.99, while rentals will be $2.99 - $5.99. What's more, the content is "portable," meaning that videos downloaded on your PS3 can be watched on multiple PSPs. It doesn't look like movies can be purchased in HD, but downloads are progressive so content starts playing a minute after you hit begin the download.
PSN users will also get a single persistent sign-on across every device that can access the network: PS3, PSP, PC. It's not clear whether those aliases will carry over into games themselves or if friends lists will start working across devices as well, however. The integration is scheduled to happen for this fall, though, so you might want to go and grab your handle of choice relatively soon.
