Lack of Dlna and MP3 won't harm sales considerably, but they might knock the top off the potential holiday peak. Harm considerably means either sales falling to the level of the competition, or ceding sales to the competition such that they sell much higher and closer to PS4 than expected. I don't expect either of these things to happen because of a lack of DLNA or MP3. It may happen for other reasons though.
