Volume was originally scheduled to launch on Mac, PlayStation 4, PS Vita and Windows PC tomorrow, Aug. 18. While the Vita release will now miss that date, the other three versions are "still very much on course," said Bithell.
Development on the Vita version is complete, but it needs some more time for quality assurance work, according to Bithell. Despite the delay, Volume remains part of Sony's cross-buy program, so people who buy the game on PS4 will receive the Vita version at no extra cost as soon as it's released.
"The party still starts on August 18, it's just that the Vita, the coolest of all the kids, will be arriving a little fashionably late," said Bithell, which strikes us as a perfectly British way to describe a delay.
