Subscription

Is there any hope to the idea that perhaps apple will form some type of subscriptions service for movies where for say $5-20+ a month you can download x-number of movies that still stay true to the current 24 hr viewing time? I am already itching to go out and get and TV but if they announced this i would run out this second and tell blockbuster what they can do with their ridiculous mail in waste of money plan... Thoughts?
