OB Kikaku has announced some new details about Initial D - Fourth Stage. As with previous seasons, Fourth Stage will feature racing scenes made entirely with computer graphics, however more advanced cell-shading is to be used to make the CG scenes a bit less conspicuous beside the traditional animation.
Fourth Stage will premiere on Sky Perfect TV Animax pay-per-view in April. A special 85-minute recap episode will be aired.
