Earliest worldwide actual first-sale month remains unresolved, so year precision retainedSony German release planned mid-January 2008; Hong Kong release planned end-January. Contemporary Les Numériques news dated January 27 states the camera was available on retail shelves, supporting January precision without claiming the first day. That news misstates video and face/Smile detection; these features follow exact maker manuals instead. No explicit manufacturer predecessor established
