People are going to bash Tanaka over and over, no matter how much anyone defends him. It was him and his team that were responsible for FFXIV back in 2010, and from what little activity there was in patching the game, delivering content and news, and things of the like, we can now see that Tanaka had no ambitions for the game and it's future -- it was pushed out the door at a very bad time in the pipeline, and the game was nothing more than a skeleton. The one responsible for this, if not solely, was Tanaka for allowing this to happen.
When we see Yoshida, we see progress. We see vision, and we see ambition. As director and producer, for 2 years him and his huge team have worked on rebuilding the game almost entirely from scratch, with a new engine, new zones, and pretty much everything used in ARR will be their handiwork, and not recycled from current FFXIV1.x. He's passionate about his job, and he seems to love what he's doing. He keeps in contact with the fans at events, he writes us letters, and news is coming (though I admit, some of it is certainly slow in arriving). With Tanaka, we never saw ANYTHING and the game never really went anywhere until they shuffled the development teams and put Yoshi-P in charge.
He has played MMOs, including the world's largest. From being a hardcore player of these games, he'll have the experience and knowledge required to make a game that is worthy of being called Final Fantasy. So far, he's doing just that - the concept art, new zones, the new (and faster) battle system, chocobo raising - all of that seems spectacular and strong, and with each new announcement, or batch of screens, or concept art, I grow even more anxious to finally sit down and play ARR for myself. I'm really excited for it.
The FFXIV team needs a strong leader who can guide the game and fulfill his vision of an awesome MMO. I believe that person is Yoshida, and he's done nothing short of miracle work since they started 2 years ago. So please, don't say that him wanting everything to perfection is a bad thing - it's what the game needs. The fans, and peers of FFXIV won't settle for anything less than perfection at this point.
