Cheaper 64gb Walkmans...when?

[yourma2000]

I've been looking for a 64gb mp3/mp4 player for a long time now and I spotted the Walkman NWZ-A847 on amazon for £190 but it was out of stock, then someone told me there was newer touchscreen series (NWZ-A86x) but the 64gb model is £300!! Two years ago I spotted a 64gb Creative X-Fi 2 for £200, since then NAND memory cells have shrunk in size and for 64gb it would probably cost the same as 32gb a couple of years ago, also a new technology called TLC NAND allows for 50% extra capacity in each cell. So with these factors, why is there no relatively cheap Walkmans? Surely the small touchscreens can't be dramatically increasing the price of these players.
