The Raid 2. Aka The Raid 2: Berandal, aka The Raid: Retaliation, aka Raid 2: Electric Boogaloo... wait...
In all honesty, the first US trailer just says "The Raid 2", but it had been rumored since 2012 (not long after the US release of the first film) that the US title of the sequel would be "The Raid: Retaliation". Nothing confirmed yet though, including whether the film will get an R rating or if they'll have to make cuts to avoid an NC-17 (every Sundance review has talked about how violent it is). But I digress
