While Street Fighter IV will feature 3D rendered characters and backgrounds, the game will still play in traditional 2D, thus creating a "2.5D" effect. While more concrete details on the game's gameplay have yet to be revealed, producer Ono has stated that he wants to keep the game closer to Street Fighter II than to its sequels, and as such the "parry system" from Street Fighter III has been dropped. A new system temporarily called "Saving" has been introduced, as well as Ultra moves. The traditional six-button control scheme will return, with new features and special moves integrated into the input system, mixing classic gameplay with additional innovations.
