I'm thinking they just don't have many people working on it or not for very much at a time. Wizard 101 comes out with new worlds (which are HUGE updates to the game) at least twice a year. Toontown relased announced this SMALL update after very long time. Their last big update was BBHQ and that was in Feb 2008 (I had just begun writing Gears).
