Yep been saying for awhile that Switch isnt just the successor to 3DS/Wii U but Vita as well.

Yep, this is basically what I thought would happen, all those niche Vita games would move over to the Switch eventually.

PC gaming is incredibly niche in Japan, mostly just MMOs.

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.

The entire handheld market is going to be on the Switch this time including devs that made games for the Vita. Switch is going to have an extremely large game library when you consider how many different types of devs it's drawing on.

100% agree. PC market has the most competition. I remember hearing awhile back that indie devs, though still releasing on pc and ps4, are finding that Switch and even Xbox sometimes result in better sales due to less competition.

Yeah, that makes sense.

Of course, that is the case. No one wants to play exotic Vision Novels on the big screen! People will want that to be private.

Erotic visual novels is pretty much the only thing that PC gaming has a monopoly on in Japan, as Sony/Nintendo/Microsoft do not want to let hentai on their system.

Hopefully all those Vita games become switch/ps4 titles and not just switch exclusive.

I said exotic, not erotic. Exotic as in Japanese.  No one wants to let other people they are weeb. Though erotic games are a good one to have on a portable as well.
