Is Blu-ray really Sony's format? {Engadget HD}

Jul 21st 2006 9:57AM HD-DVD players can play DVDs and CDs as well.
HD-DVDs are faster and 30 GB is enough for a HD movie and extras. More disks could be used, they do it now with DVDs.
No one uses disks to record to anymore, just backing things up to keep, and this is where the speed helps.

I'm not even considering Blu-ray at all anymore.
