Yoshida never worked on the XI. Tanaka has always been the producer of the XI. Director of FFXI was Komoto until august 2010, then Matsui until december. Now it's Mizuki Ito who was the director of abyssea.
FFXIV went from Komoto and Tanaka as director and producer, then Yoshida (who seems to come from nowhere) for both.
That's the summary of the directors/producers for the 2 games.
(and here we see that Komoto was director of both games for a f*cking long time... he should have left FFXI sooner, to spend more time on the XIV)
