There is good news for HD viewers-- HD rentals will be available, but they'll cost an extra buck (so $3.99 and $4.99 for library titles and new releases. There'll be 100 HD titles starting today, and more all the time. And of course, movie rentals will be sync-able with the iPhone and iPod, or have the ability to be downloaded straight on to the revamped Apple TV. Unfortunately, we haven't heard an official resolution on the HD (720p is one of the numbers being tossed around, and that's not great for serious HD viewers), but if we get to see one of these flicks, we'll let you know.
Get out the popcorn-- it's time to rent some movies from iTunes!
