Sony Japan today announced the DSC-P30 and DSC-P50 which we'd previously seen / announced at PMA 2001, they also announced an upgraded DSC-F55 named the DSC-F55DX, still fixed lens but now with a 3.34 megapixel CCD (but as with the F505V only using 2.58 megapixels of it) and some updated features. UPDATE: This will be a JAPAN ONLY model.
