Sir T said: "The extra capacity IS a benefit in two ways. It means that it will support lossless audio and video which takes up more room than lossy audio and video signals. The less compression used, the better both will look and sound. Also added storage means there is plenty of room for any new A/V technology that comes in the future."

No argument there. My point was just that the average consumer might not care all that much about the storage difference between the two formats, only that they will allow significant improvements to audio and video. Both BluRay and HD-DVD will support Dolby Digital+ and DTS-HD, as well as the lossy versions that we have now.
