Can anyone point me to statistics involving Percentage of:

1) Brick and Mortar Rentals (Blockbuster,Hollywood, mom and pops, etc)
2) Online rentals (Netflix, BB total access)
3) Pay-per-view rentals
4) XBOX/Amazon/ITunes -- "downloaded" movie rentals

My goal is to use statistics to make a case that, even with high bandwidth, downloading movies will always co-exist with physical media -- no matter what Microsoft says. I'm gathering different info to try to support my case. Any advice, info, etc would be appreciated.
