I would like to see the actual sales numbers (in $) rather than percentage and also the sales of physical medium.
I do not consider the Zune marketplace a contender. Last I checked their movies, especially rentals, were crazy expensive. Also, I get tired of M$ and their crazy pricing schemes! RAWR the points are confusing and annoying. I hate iTunes enough as is, I don't want a service even more inferior than Apple's!
I don't buy movies online anyways. They are usually as much as the store price for the physical version (including blu-ray) and I don't get the full quality or all the stupid features. Also, the audio is usually only OK. Also, the sales and the price decrease overtime for DVDs/Blu-rays are more common and better than their online equivalents.
