Where in the hell did you get these numbers? Warner is including the PS3. There's no way 6.2 million dedicated BD players are getting sold this year. Look at their movie projections and you'll find attachrate for each format. Despite having and estimated 6.2 million BD devices the movie revenue isn't expected to outstrip HD DVD by that much because most of the BD players are PS3
My interpretation of the presentation is sold to retail not sold-thru to customers and all these numbers are based off of global manufacturer projections (Shinco suggests such). The PS3 is expecting to ship and sell 6 million units worldwide by March and it's pretty safe to say that they are going to try and at least do 10 million through 2007 to compete with M$. Therefore 6.2 million would not make sense if it included PS3.
Also, looking at the manufacturers listed for HD-DVD: Toshiba (big seller), Shinco , Alco !!!! That 2.5 is including players from LG and Sharp and probably accounts for 40% of the numbers. So that's 1 million which we can say is also apart of the Blu-ray 6.2 million. Which leaves Samsung, Pioneer, Panasonic, Phillips, and Sony to make 5.2 million stand alone Blu-ray players about 1 mil a piece.
I could be wrong but, like I said, that was my interpretation of their numbers.
