For everyone who finds statisitics interesting here are 2 links to both Blu-ray and HD-DVD information that some might find useful (and/or interesting). Not sure how often they are updated though.
I'd be interested in USA vs UK sales as out of the 23 HD DVDs and Blu rays that I own, only 2 have been purchased from the UK. Do all the people importing from the UK count towards USA sales?? Is all the importing having a negative affect on the price of UK discs (they seem to be going up in price)??
