I have Scholar's Silver Series X and I'm planning to upgrade soon to Gold. I am wondering if I should just wait until 4.0 comes out. Does anyone know how pricing works on upgrades? Would I gain more bang for my buck by waiting to upgrade? I'd hate to upgrade to Scholars Gold 3 and then see 4.0 come out by the end of the year if I could have saved money by upgrading directly from Silver X to Gold 4.0.
