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.

Sony DSC-F55DX Specifications

UPDATE: A source has informed me that the F55DX is essentially the same as the F55V (announce a while ago) with new firmware which is closer to the P-1, P-30, P-50.
