Agere Systems announce that they will produce a new Chip set for future Sirius radios. The new chip set is smaller and used less power consumption. Jim Meyer of Agere says "Demand for SIRIUS products and programming is growing rapidly, Agere continues to be a valued supplier, as we introduce new and innovative features in our next-generation products that, we believe, will attract additional subscribers." This can only lead GSI to the assumption that the next-gen of sirius radios will be smaller units. Time will tell.
