I don’t.
Sony has a much more mature internal production line with TFT LCD. They haven’t even began using OLED in their phones in large scale, so expecting them to use it on devices with an even lower production quantity is highly unrealistic as it will drive cost up while lowering profit, which is not desirable with low volume products.
Didn't Cowon S9's have OLED screens years ago? They were around $300.
