EA Sports has teased a possible sequel to NBA Jam, a long-running fan favorite basketball title. NBA Jam made a return back in 2010, where it landed on the Nintendo Wii, and later on it jumped over to the Xbox 360 and PS3. In 2011, an enhanced downloadable version was released called NBA Jam: On Fire Edition, which offered gamers gameplay improvements and new features. EA hasn't announced an NBA Jam sequel yet, but it is teasing it through Twitter, which is an interesting way of doing things, especially for Electronic Arts.
