Thats an opinion of course. But a lot of what I am laying out in this post is fact.
Nope. Most of what you are presenting is hearsay.
Whether or not there are "not a lot of manufacturing plants yet" is really meaningless. You can always convert plants or build new ones as needed. The point is, Blu-Ray discs have more capacity per layer per side than HD-DVD. End of story.
I own over 50 Blu-Ray discs, and have rented even more than that. So far I have not seen any issues with Blu-Ray discs not working or not playing due to spots, scratches or whatever else. Besides which, ALL formats suffer from occasional bad batches. I've occasionally had to return regular DVDs over the years due to manufacturing issues. So far I haven't had to return any Blu-Ray discs, but I guarantee that all formats (DVD, HD-DVD, and yes, Blu-Ray) will occasionally have bad batches where something buggy happened while making the discs. The companies producing Blu-Ray discs use special coatings to make the discs scratch resistant as well, making the whole scratched-surface argument pointless IMO. Are you going to take care of your discs or use them as frisbees?
The Blu-Ray specs are in place as well. Blu-Ray is currently using LPCM, but can also use any of the DTS and Dolby standards. Your comment that "you have no idea what you are going to get on the Blu Ray side" is garbage. There are only so many audio standards out there for video discs and Blu-Ray is designed to be backwards compatible by making important older codecs mandatory. Blu-Ray players are designed to support at least the mandatory codecs, so you do not have to worry about being able to play audio or video. Audio is not and will not be an issue.
As far as PS3s working with BD-J (Java). They will work, all that is required is software/firmware updates to the PS3. Java is a programming language, so all it would require is an operating system (or operating environment, or user interface environment - i.e. an embedded software or firmware OS like every preprocessor and digital source unit already has) that can execute Java runtime code. You can run Linux on a PS3, and Linux runs and executes (as well as compiles) Java source code. I should know, I used to do a lot of programming in it.
Stop trying to scare people...
