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.
The poor Wii U sales were felt across the entire platform. Not just the Yakuza games. I can understand why this may make them cautious for Nintendo consoles here on out. However, it's a shame all the same. I'd have loved to play Yakuza 0 on a portable console like the Switch.
