Worldwide Blu-Ray will (probably) represent 33% of the Disc based movie market in 2011 (with DVD remaining at 66%), and I expect (legitimate) movie downloads to represent 20% of the total movie market in 2011. After 2011 I expect people will move towards digital downloads at a faster rate than they adopt Blu-Ray, and by 2016 digital downloads will represent over 60% of the market.
Realistically, digital downloads offer the convienience features that drive rapid adoption of a new format; the limitations of bandwith, and trust in download services currently limit people from jumping to these services but these become less of a problem every day.
