Street Fighter IV is a recently-announced fighting game, and the continuation of Capcom's long-running Street Fighter series. It was announced in London on October 17, 2007 at a press conference Capcom was holding.  The teaser trailer showed Ryu and Ken squaring off in a pre-rendered 3D brush stroke-painted style, but no actual gameplay was shown. Capcom has stated that the game recently entered development.
Speculation has commenced on whether the game will feature 3D CGI-style graphics or traditional Street Fighter 2D hand-drawn animation.
