We are certainly working on new projects - we always are. We try not to mention them until they have at least resulted in a working prototype which we like. Sometimes an idea is abandoned for a long time and then revived - for example Eros was prototyped 5-10 years(?) ago before adding a shunt regulator brought it to life.
It's hard to predict which ideas will sell well enough to keep active - for example, the short-lived Seductor, based on an idea I'm still refining. (The prototype 50-watt version was a sonic disappointment and never made it to kit status.) Foreplay came back from the dead in version III, then retired again before Moreplay was created to fill in that functional spot.
