Quick question.. I am considering switching to iTunes for my movie purchasing. As technology progresses and we are eventually able to download movies in full 1080p resolution, or better, do you think Apple will offer discounts for upgrading previously purchased films to the latest and greatest version? I have noticed the iTunes plus upgrades and am hoping that their movie store follows suit. Also, any chance of iTunes downloads reaching Blu-ray quality an time soon? Thanks for the responses..
