HD DVD is compatable with older DVD and will support playback of regular DVD.

Correct. HD-DVD players can also read CD media.

Somewhat correct. They require additional hardware capability to refocus the laser for DVD compatibility. This adds greatly to the cost of the unit... Early prototypes and demo untis used dual laser mechanisms to provide DVD compatibility. Most of the first generation Blu-Ray players don't read CD media as an additional laser mechanism is required.

Correct.

It requires changes to production, but nowhere near as drastic as the HD-DVD camp would have you believe. In fact, Sony's Blu-Ray replication process is very cheap to buy into and economical to run. On average, Blu-Ray titles are $8 cheaper than HD-DVD titles when comparing MSRP. It's all protected under NDA, but a lot of industry watchers believe that Sony is keeping prices low by requiring studios to adhere to their pricing standards and while the Blu-Ray players are more expensive, Sony is trying to beat the HD-DVD competition with lower prices for movies combined with increased retail exposure. I'm not sure how Sony is going about it, but Blu-Ray exposure in retail stores is very up-front and highly visible. HD-DVD has since been pushed to the side at most stores.

No. And concerning durability, both HD-DVD and Blu-Ray just plain suck. Just as DVD is more sensitive to scratches and dirt, smudges, etc.. compared to CD. So are the new HD formats in comparison to DVD. Panasonic had it right when they started to put DVD-RAM in a protective shell. Sony did it right with XDCAM and UMD, but still opted for the bare 5.25" disc for BluRay since everyone is so familiar with these things.

Yes, and so is HD-DVD. :-(

HD-DVD = 15GB (about 14.5GB actual) per layer, max of 2 layers.
Blu-Ray = 25GB (about 24.2GB actual) per layer, max of 2 layers for now - Sony claims up to 12 layers with future revisions.

All formats are temporary, regardless of the media they come on. HD-DVD and Blu-Ray won't be the last disc based formats to come along. There will always be a need for a tangible media or storage method to place data files or movies or music onto. The spinning optical disc is going to be with us for a long time to come... The next wave of storage advancements will bring solid-state devices, holographic media and other exotic technologies demonstrated over the past several years. IMO, holographic media will be the next big storage advancment. It can work off of spinning disc type media or stationary media like something the size and thickness of a credit card. It could easily have multiple layers just like current optical media does, but instead of tiny little pits or grooves in a reflective film inside the disc, it would have holographic dots. Just like looking at a hologram, the image that appears 3D as it changes with the viewers' angle of view, a holographic media would present different data depending on the angle at which the laser enters and reflects off the data surface. Now you have a media that can have the same data density as HD-DVD or Blu-Ray, but the data presented for reading/writing changes with the angle of the laser. In holographic storage, if the read laser can change angles from 10 degrees to 170 degrees horizontally in 0.2 degree increments, and the data "dots" are the same as HD-DVD, then it would store 800 times as much data in the same space as HD-DVD!
