aye, while i'm a little annoyed that my DVD collection will become obselete in maybe 6 years time as they all get re-released on whatever becomes the dominant format, with more extra features than ever (and HD-TV support), i kinda welcome the move to a new format...
the DVD format has reached its limitations, both for games and for video, and it is quite apparent - the way the subtitles are handled sucks, IMO (though it doesn't seem like they care about that), and LotR not being able to fit on one disc, as well as the fact that it only does 480i/p...
that's why i'm an avid supporter of Blu-ray, its much more future-proof than HD-DVD is, i can't imagine HD-DVD being able to fit much extra features on one disc if they put HD video on it, and they'd have to go with multiple disc "Special Editions" again, much like DVD. personally, i'd much rather prefer it if everything was on the one disc. as people have pointed out, 54GB may seem like a heck of a lot now, but will it be, in, say 4-6 years time? i mean, 7 years ago, i lived with a 1.6GB HDD, nowadays, i wonder i could've survived with 60GB, let alone 1.6GB...
if you ask me, if HD-DVD becomes the dominant and mainstream format, there would probably be more format changes than if Blu-ray was - i don't think HD-DVD has enough storage space to be very good at being future-proof, and before long, we'd need another format to satisfy our needs...
and those who say they don't like the big companies forcing new formats down our throats, IMO, its the only way for consumers to adopt new formats - usually the early birds and tech heads jump on board the bandwagon real early, but it takes a hell of a long time to get the majority of the population to get into it, without forcing it upon us, it'd take forever...
especially about waiting till most people got into HDTV, the thing is, it seems more like the video medium and its capabilities that encouraging people to buy HDTV sets and such, not the other way round, if we were to wait for HDTV to become mainstream before introducing new formats, it'd take a long time for people to snap it up - if they don't see much advantages in adopting to it, they simply won't. you can see this in Australia, HDTV has been available for almost 2 years now, but hardly anyone has adopted, the huge, vast majority are happy with analog TV as it is - however, widescreen TVs are taking off real well since most people have DVD players now and would like to watch them in widescreen (same is the case with surround sound systems).
