actually zog your right, but you could market a multi player like this - i.e. plays hd-dvd and blu-ray. It would simply come down to using 2 different lasers in the player, something that is already done on many cd/dvd players. Someone will surely do it. The thing about this ‘format war’ is that it’s all hype to sell product by both camps. This is nothing like beta max vs. vhs. not only was this at a different time, but the media were phsically different in vast ways, requiring seperate units for either a vhs or a beta. Unlike hd-dvd and blu-ray, which only require a different laser. Of course that may not even be the case either, i mean i’m almost sure i read a story here a few days ago about hd-dvd going to blu lasers also.
