Electronic Arts officially announced Battlefield 4 for the Playstation 4 and the Xbox 720 but there are only some further information about the next-gen shooter known.
Battlefield 4 will use the Frostbite 2 engine using 80% of its possibilities. As a comparison: Battlefield 3 is only using 30 to 40%, meaning the graphics will improve a lot. The Xbox 360 and PS3 were released 2005, and a new console with whole new hardwear is really necessary in my opinion. Last week, Gamestop had their eyes on an alpha version of the game - and they said it's awesome regarding gameplay and graphics. Unfortunately, the release date of Battlefield 4 is unknown.
