One megabit or one megabyte?  If the former, they lie.  However, I
have heard of 192Kbps for stereo CD quality, with 128Kbps well in
sight.  128Kbps would come out to about 1 megabyte/minute.  The Sony
is doing about 300Kbps, which is still pretty respectable.  One thing
I forgot to mention is that these 2.5 inch mini-disks will be writable
too, so the compression stuff has to be cheap enough for commercial
gear.
