Amazon Unbox HD Rentals Coming Soon?

Amazon's Unbox service might finally get some HD action. This screencap is from a survey sent out to their customer panel—notice the $4.99 pricepoint to rent an HD movie is the same as iTunes. Where's the "cheaper, plz" option? They also asked whether there's interest in subscriptions—like to "hit movies," or say, indie flicks. What say ye? [Thanks Michael!]
