If you think the Yakuza series would be warmly welcomed on Switch, you'd be of a different opinion from Daisuke Sato. Mr. Sato is a series producer on Yakuza, and he doesn't think it would make sense to bring the franchise over to Switch. His main reason is because of poor sales for Yakuza 1 & 2 HD on Wii U. You know, poor sales on Nintendo's worst-selling console, for a compilation that never even left Japan.
UPDATE - Here's the full comment from Mr. Sato.
“To be realistic about what happened, Yakuza 1&2 HD for Wii U was a huge failure. But we are always looking to develop for multiple platforms as much as possible and know that brings in a greater audience to attract more people. However, as far as Switch is concerned, I’m convinced that it isn’t the ideal platform on which to develop Yakuza games. Maybe people don’t expect this kind of game on Switch. Maybe they’re used to different games. It may not be the ideal platform. As for Xbox One, we can consider it, knowing that Xbox One users may be more likely to be interested in a game like Yakuza. This could potentially be an option.”
