IMO, Tanaka is one of the Best in the Buisness. Always has been, always will be. People just do not understand that Directors and Producers do not get to decide when a game is released. There is a whole Flock of People above them and yet more people above those people. The game industry, especially at the size of SE, is a monster of corporate hierarchies.
What really drives me crazy is that Yoshida blindly gets credit for everything being done over this past year. I hate to burst people bubbles but, with the exception of system and class overhauls demanded by players, most of what has come out was already in the planning and development phase. I'm not saying he hasn't put out any good ideas or added anything, but don't go bad mouthing Tanaka while crediting Yoshida with things that were likely started before he took control.
