Universal confirmed the next Fast & Furious franchise title, Furious 7, in a recent Facebook post. They confirmed this by releasing the first poster for Furious 7, they also made mention of a Furious 7 trailer release coming sometime next week.
With The Fast and the Furious, 2 Fast 2 Furious, The Fast and the Furious: Tokyo Drift, Fast & Furious, Fast Five, and, most recently, Fast & Furious 6 and now Furious 7 taken, I think Universal is running out of titles. The trailer will be released at an event in Los Angeles, Jason Statham and Kurt Russell will join returning stars Vin Diesel, Paul Walker, Dwayne Johnson, Michelle Rodriguez, Tyrese Gibson, Chris Bridges (a.k.a. Ludacris) and Jordana Brewster. Furious 7 opens April 3, 2015.
