equipment will eventually getting cheaper and cheaper, cause ppl will spend money and buy good eq for their current level and when they proceed in level, they will sell off back into the system. while new player will keep poping more nice eq and only more eq introduced into the system and no eq eventually will goes missing unless player sell to merchant or stop playing, so eq price will keep on going lower when more of them are available. diablo should introduce some kind of aging for EQ, ie after certain amount of days, equipment will retire or slowly dropping in stats.
