Lngbruno: XRCD is not a "format," it's just a marketing term for a very good mastering process involving a little bit of technology and a lot of care. Given that there are few audiophiles out there, it would never pay the majors to spend the extra time/money to do better mastering. So you'll just have to enjoy XRCDs when you can find them.
As for your other concern, even if a label has gone under, somebody owns that music. Rest assured, if they decide there's a market for it on a new format, they'll bring it out. (But don't expect SACD or DVD-A to solve the mastering problem.)
