I think the newer composite fuselages allow for the greater differential while maintaining fatigue life of the hulls.

DO YOU GUYS NOT READ WHAT I TYPE!?!?!

I never said anything about 10,000 ft being standard! It has to do with cabin deferential pressure at 8.4 psi. This would put your cabin at about 6,000 ft if you were at FL370. In other words, Denver Colorado field elevation. You would have to go to FL410 or FL420 to get to a cabin altitude of 8,000 ft.
