According to this estimate the most costly components of the PS4 were the CPU, GPU, RAM and hard drive:
A hybrid would add a display and battery.
For which of these components Sony has a "vertical monopoly"?
They aren't in the GPU, CPU, RAM or Hard drive business. They are in the memory card business, but when we look to the Vita and PSP (Memory Stick Duo), their memory solutions were never competitive to SD and MicroSD.
Their own manufacturing plants for mobile displays were shut down years ago: https://en.wikipedia.org/wiki/Sony_Mobile_Display
The Vita displays and most Xperia displays are made by Samsung instead of Japan Display, Inc.
One of the very few Sony components in the Vita and the Xperia phones is the battery.
