I'm glad I can check the movie out day of release with my Roku.. but is it only in SD? Other than watching it on my Kindle Fire the movie will be less than gratifying if it's lousy resolution on our HDTV.. hence getting a Blu-Ray copy in the first place. Even DVDs up convert but non-HD streaming from Amazon Video doesn't convert itself.
I was wondering this myself. At first I was thinking, "Well it sucks my BR won't get here until Monday but I can at least watch the movie Saturday on my TV with AIV." But now I'm worried that the instant video will be in standard format, and it makes me wonder if I should just go out and buy it from a store instead.
