Also the reason there was a Dragon Quest event is it was to celebrate DQX's first anniversary of service, a game that was actually Yoshi's previous project (he left the DQX team to take up his post as producer of FFXIV in 2011 following Tanaka stepping down due to FFXIV 1.0's bungled development and launch).

And as Youkulm mentioned, the creator of Yo-Kai Watch is close friends with Yoshi so, yeah, there you are (and I want to make it clear I am definitely not accusing Yoshi of nepotism here as I have so much respect for him and the FFXIV team - if it came across that way I am deeply sorry - it's just that crossover events that are run in FFXIV with other games and series usually have to have some deeper connection to FFXIV itself and the development team in particular, and are not just added "because it's requested by players"). So again, for that reason I say a KH themed event in FFXIV is highly unlikely. That's just facing facts.
