I think it covers a lot of bases which have already been discussed to death. The question of technical quality is still very much up in the air since both sides have obvious advatages to each other. I think that for people who just buy discs locally and enjoy them - which is most consumers - then it is just the HDi features which offerred HD DVD any real advantage.
Cost is often used, but consumers chose, this holiday season, to buy the more expensive Blu-ray players at levels which basically eliminated all HD DVD leads built up to that point... and that's completely ignoring The PS3 Effect. Consumers chose to spend more on Blu-ray at a time when Warner was neutral and Universal and Paramount were exclusive to HD DVD. They cleary didn't buy based on price of players... and it's hard to know if Disney/Sony/Fox was really the motivation for people to go Blu. More likely it was the far superior collection of CE choices in the Blu-ray format vs. Toshiba.
At the end of the day, every company is in this for the money. If the studios could make good money on both formats, they would continue to do so. But, the belief I have, and Warner has stated - a single format breeds consumer confidence which encourages adoption and spurs sales.
It follows as a general A/V law - If sales increase, then manufacturing will increase and pricing will decrease as competition within the format grows. We could see the start of that this holiday season... especially from CE manufacturers who deliver the full package of playback, surround, and video. Panasonic, Sharp, Sony, and Samsung will likely be leading that list.
The format war is over, and consumers win when all studios release all titles at the same time, or ahead, of the DVD release. Beyond that, the majority of people that are complaining bought into a format with far less support from day one, from a company that has incredibly high vested interest in the DVD format - and went against the grain of every other major CE manufacturer in the world. Their choice to do so, but HD DVD had the writing on the wall over two years ago and to their credit, they definitely have hindered HDM adoption by the masses.
