Look at the top selling systems in Japan of all time.

1. DS
2. GB
3. PS2
4.3DS
5.PSP
6.PS
7.NES
8. SNES
9.GBA
10. Wii

Look at the timing of Sony's devices making the list. Look at the massive contraction of their home and portable market. Look at the rapid changes the Japanese gaming market has taken, and finally look at the Switch.

That's really the only perspective you need on the issue.

Pretty sure 3DS is no.3 on the list, it passed the PS2 some time back.
