Possible Sony WM1-Series successor spotted online
This was posted on what looks to be some social media website in China. We can see the Walkman logo in the lower right corner of the device, clearly indicating this is a new Walkman device.
Update: Another photo showing the front. Thanks to @mirai160525 for twitter for the photo.

The gold colour remains, along with the microSD slot which is located under the hold button. Good news is that Sony has moved to USB type-C for this new model, away from the WM-port. The original post claims this will be running Android which is unfortunate since battery life will not be as good as the older model, but it should allow for streaming service functionality.

For other specifications we are most likely looking at the same screen size, 4 in, with HD resolution, USB type-C, Bluetooth (possibly 5.2), along with WiFi. Hopefully the USB-DAC function remains, since this is absent from the NW-Z500 and NW-A100 models. The controls will be on the right side, like in the current model.
There are still some unknowns, are we looking at a new Signature series model? If so, perhaps this could indicate that Sony will release new Signature series headphones to go with this new Walkman when this is released. Will there be 2 models again, the WM1Z and WM1A or just one?
What released timetable are we looking at? Fall 2021? Winter 2021? Or Early 2022? Nothing has appeared on any certification sites and if this will be rocking Bluetooth and WiFi, it will need to go through certification. If we are seeing parts leak from China, then perhaps we might be looking at a Holidays 2021 release.
Finally, what will this be called? WM1Z mark 2? or WM2? Post your thoughts below.

As always, if anyone has any information please contact me or post the information in the comments below.
