New unannounced S-Series (NWZ-S754)
Engadget has more photos of this new unannounced new Walkman, the NWZ-S750. Engadget claims the screen is an OLED since it has high contrast but that remains to be seen. Capacities could range from 8GB up to as much as 32GB, since the NWZ-S754 is 8GB, then NWZ-S755 would be the 16B and NWZ-S756 could be the 32GB. The new S-Series will feature Noise Cancellation like all previous models and like the new E-Series will feature interchangeable wallpapers.
