Earlier this week, EA Sports revealed that boxing greats Muhammad Ali and Mike Tyson would appear on the cover of Fight Night Round 4. Now they've released a trailer answering the obvious question posed by that cover: "What if those two guys fought?"

FNR4 sports a new graphic engine that will lead to smoother animations and a greater variety of fight styles than prevous installments. Ali and Tyson's distinctly different styles were probably the reason why they were chose as cover athletes. Well, that and the fact that were ridiculously good at punching people.

Fight Night Round 4 will be released in Summer 2009 for the PS3 and Xbox 360. Playable demos will be released for each version prior to the game's launch.
