That's because they're retarded with how they went with Vita. They could have made enough traction had they given it some love.
I mean I'm not surprised they're doing this bad in their handheld division. Speaks magnitudes with regards to their Xperia line up as well.
They can still pull this off if they are smart enough to find a way to integrate their Xperia line up with their Playstation brand. No, I don't mean Remote Play. I mean exclusive games for those. To achieve this though, they won't be able to use Qualcomm chips as they're very bad compared to Tegras.
I mean just do these checklist and you probably have a chance in the market.
-Modified Android OS. The closer to AOSP the better.
-Stop treating it like a regular PS on the go and defirentiate it
-Integrate or partner with Google to allow Google Play apps to work on it
