At the Xbox One reveal, EA has announced that EA Sports will be partnering with Microsoft and deliver exclusive features for the new sports games from these four franchises: FIFA Soccer, NBA Live, Madden and UFC. All four games will be launching within the next 12 months. They will also be powered by EA Sports' new gaming engine, EA Sports Ignite, that (according to the publisher) will blur the line between the real and the virtual.

According to the conference, the engine will feature 4x more calculations per second, 10x more animation, dynamic environments, greater speed and agility and a greater field of vision, which will culminate in a greater human intelligence for the AI opponents. Microsoft even had several athletes vouch for their respective sports games' realism and dynamism.

Concerning the trailers, the graphics themselves looked somewhat better than a standard Xbox 360 game (even if not by that much) --however, the fluidity and flexibility of the players' movements  looked very impressive. You can check the videos below and make your own opinion.
