Once a single is format is established you will see a how the market makes the slow but certain transition between one format to the next. As HDTV prices drop and having a LCD display becomes the norm in many households more people will begin adopting the new technology. And don't forget computer users, never forget High Definition is not only about "movie players" is also about storage capacity for PC/Mac users. A single format will also mean the winner will take flight for computer users, and you will begin to see PCs coming with standard hi-def roms and certainly later hi def burners. DVD dual layer media is still selling at ridiculous high prices but that will change, once hi-def blank media starts to gain popularity and burners drop below the $400 price range. There's a lot of Hi Def content you can enjoy on LCD monitors besides blu-ray/hd-dvd movies, many already own hi def video cams and you can also burn a lot more in 25GB/50GB of all those hi def ripped movies you can get around there....not to mention your own hi def content, video, pictures, etc. More space is always welcome, and let's face it, 4.37 GB in a single layer DVD SUCKS, and I wonder who buys dual layer discs at such prices (over $2 per disc). I'm tired of having to split my videos over so many discs and I'm sure A LOT of people think the same, and I'm not even burning anything close to hi def yet!
The transition will come, sooner than later this time. Because if something is true is this : Technology never stops.
