There is a huge amount of doubt until Japanese gamers show that they are willing to buy full price retail Switch games from publishers other than Nintendo.
20k for God Eater 3 is pathetic even for it being a late port. YW4 sales were miserable. Other than Minecraft which sells on pretty much everything there has yet to be any major standout third party title on the Switch, so why would third party publishers want to focus on the Switch if the audience isn't buying their games in even slightly impressive quantities?
You don't think Dragon Quest 11 S will sell well? How could it not?
I mean, I wouldn't be surprised at all if it underperformed to some degree. Not because there's no audience for DQ on Nintendo platforms, the 3DS release did great. It's just that t's more than two years late. Should still do well, but any comparisons to the PS4 release will need to be done with the extenuating circumstances in mind.
