Sony NW-ZX100 leaked, sort of
The shots are rather poor but it gives a good general idea of what to expect, basically a thinner device by the looks of it and probably a non-touch screen. So perhaps instead of replacing the ZX2, the ZX100 will slot under it but above the A20.
If anyone has the link to the Digi-wo post or article where the original images are found, please leave a comment with the link.
