Actually there already have been several launches of Music DVD and 'better than CD quality' audio.... much to the snoozes of the consumer public. Like you said it takes a much bigger leap in quality (or more importantly PERCEIVED quality) for a new technology to take root with most consumers. Blu-Ray and HD-DVD will look kick-ass on those of us with HD tvs, but on your still more common 27" tube set most consumers won't see much difference. What really helps new technology is a 'gimic' of sorts. I personally never would have thought PSP video would almost instantly have shelf space in Wal-Mart of whatever. But people like their portability. Go figure!
