Fleischmann has announced their new line up of models for 2006 which includes steam and electric locomotives with sound (HO Only). Interestingly they seem to have allowed Trix to corner the Bavarian locomotive market while they concentrate on new Prussian models. They also appear to be playing it a little conservative by not producing an N-Scale Steam Locomotive with sound to answer Minitrix's version.
I'll have to ask them about this at Nuremberg!
