Comcept will be making official the delay of Mighty No. 9 during Gamescom, according to a post on the backer forums.
As reposted at NeoGAF, the delay will be announced during the show to the general public, and will be for all platforms and distribution methods. At this time, the game is aiming for a Q1 2016 release.
The post cites bug fixing, including issues pertaining to the game's online features, and also notes that half of the backers have yet to respond to the platform survey. A new survey will be sent closer to the game's release.
