Maybe STP need to refresh their drive as a band. Alot of bands need to do it, actually.
Instead of putting out one album every 2 or 3 years, maybe they could do something like a 5 or 6 song disc every 6 months or so. That way it would show the progression of ideas better, without so much time between, and it's not as much pressure as with longer releases.
Green Day are supposed to be putting out a 3-part album over the course of the year (unless that idea has changed now). If they are 3 full length discs, however, people will be pretty damn sick of Green Day.
