News to me about the PC thing, Japanese publishers actually seem to be relying on the platform more and more, if anything. Then again I guess what I mostly know about are AAA and AA titles, but even recently there was a really niche Asian game that sold very well on Steam (honestly can't remember what it was, my bad). I think they sell pretty well if anything.
Switch is definitely a much safer bet though. Less competition overall and a lot of the Switch audience is probably inherited from the Vita.
