I don't think he was joking. Yoshi-P probably wants to play it just as much as anyone else.
If I recall correctly, they had a Live Letter (scheduled FFXIV livestream with him and a few others) right after Tears of the King came out and he had his Switch with him when they were still setting up.
"Xbox...not a platform for fans of Japanese games".
Are people really surprised by this?
What big Japanese games have ever been exclusively for Xbox?
Blue Dragon? Lost Odyssey? Both of which would have been more successful on Playstation, or at the very least whatever Nintendo console was relevant then.
Honestly, it just a bad time to be a fan of Japanese games in general.
No one in Japan has an Xbox and the vast majority of people outside of Japan with one didn't buy it to play anything Japanese (nor have they ever).
Anything getting released on Playstation out of Japan is getting censored one way or another. Anything weird or crazy or violent or sexual is fine in Western developed games, but when it comes to Asian ones, then it's too much. It's almost as if Sony hates Asians.
Nintendo's hardware is so old, you'll be lucky to get more that 20 FPS on anything multiplatform, and no one wants to make anything exclusive for it because they have to compete against Nintendo.
And if it's on PC, it's either a terrible console port or isn't made because no one in Japan games on PC.
