I THINK I read recently that Airbus are looking to increase cabin pressure to lower cabin altitude. So if the industry "standard" is to keep cabins at 10,000MSL - the new standard will be 8,000MSL.

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