Marvel And Netflix Reveal Defenders Premiere Date

This new teaser shows the Defenders,  Daredevil (Charlie Cox), Jessica Jones (Krysten Ritter), Luke Cage (Michael Colter), and Iron Fist (Finn Jones), in an elevator via security footage at the Midland Circle Financial. This is the front company the Hand was using in Daredevil Season 2.

Jessica Jones notices the security camera and destroys it. The footage ends at timestamp 08:18:20:17, could this signal that Marvel's The Defenders will release on Netflix on Aug. 18, 2017?
