Since all the Europe 300 models have DLNA and the 350 in the US does it would appear they have the same similar circuitry. It would be puzzling if for a $30 MSRP price difference Panasonic would design different hardware between the 300 and 350. Also if the hardware was different why would they be discontinuing the 350 so rapidly?
You could be correct and if they never implement DLNA on the 300 US models we will never know.
