if you add "with 3rd party software" after "OS X can" then yes, you've got it straight.
It is looking like Apple expects what I've been expecting since they announced the two formats wouldn't merge 3-4 years agoboth formats fail.
Toshiba will end up losing less money in the long run because they pulled out sooner. Notice that Disney/Pixar (Steve Jobs) aren't releasing all of their big-time movies that they already have HD masters for on Blu-Ray? Only titles that have come to DVD since BR and HD-DVD hit the market are available.
No Finding Nemo or Incredibles or Monsters Inc or Lion King or Fantasia or Mary Poppins or Sleeping Beauty. They are waiting for the format to die and investing as little as possible to keep up appearances in the mean time. Either we'll see a new HD physical media (unlikely) to bind them all, or we will see the effective end of physical media. Blu-Ray won the HD video optical disc format battle, but they are 3/4ths of the way through losing the larger war. Bandwidth may seem to be lagging behind (in most of the country, it is) but it grows exponentially, not linearly. Just a few years ago, stereo audio files required a non-trivial amount of bandwidth for the average user. Now they are essentially instant in most urban and suburban areas. hard drives are in the middle of their biggest change since the multi-platter disc. SSDs will keep halving in price and doubling in capacity every 6-12 months. That means 2TB SSDs for 300 bucks in just 3-4 years. That, coupled with a 20-40mb/sec FIOS connection equals large-scale local storage of HD video the way people store audio on their computers today. In the time it took DVD to overtake VHS's corner on the market, Blu-ray will go from the latest thing to commercially irrelevant. I've already copied all of my DVDs to a 750GB drive so I can stream them up-converted onto my 360 from the Mac Pro upstairs. The discs themselves are in storage now, except for a couple special edition packages that I like to look at! Physical Media is dying. My company sells BR discs, and I can tell you that they are less than 1% of our total physical DVD sales despite a lot of marketing efforts and a material that should benefit greatly from the benefits of HD (music performance).
SACD will be around longer as a money-making format than Blu-ray will, because there is no easy replacement. Blu-ray will only live on as a relic, and as the physical substrate for PS3 games.
