Sony to introduce another Walkman at IFA along with new A-Series?

It appears Sony has another Walkman in the works, another ZX model, the ZX100.  Not much information on the FCC website except NFC and Bluetooth from the looks of it.  I cannot seem to find any information about capacity.

Sony Planning update to A-Series?

It seems a new Walkman has popped up on the FCC, the NW-A20, 3 models, A25, A26, A27.  These seem to mimic the current A-Series, A15, A16 and A17, so perhaps this is just a memory bump but it seems this is not the case.  The A25 is 16GB, A26 is 32GB and the A27 is 64GB.  External and internal images are due to be available on the FCC in early September, so perhaps an IFA debut again?  From the documents, not much is known, rear design seems identical to current device. 

LDAC Support for Sony A-Series (NWZ-A15/A17)

As mentioned back in early February, the LDAC update has made its way to Europe.  It seems the update has been available since early April (4/10/2015) so I apologize of not update the blog with the news.
