Thatgamecompany's critically acclaimed game, Journey, has recently received a release date, according to docs.playstation.com.
Sony announced that the port of Journey would be making its way over to PS4 last year at GamesCom, and in line with their expected launch date of "mid 2015," Journey could be arriving to PS4 on July 21, according to the docs. Sony has yet to make an official announcement on the subject.
From the Grammy nominated music to the deep story, Journey will be upgrading itself to beautiful 1080p with 60fps. For a bonus, anyone who bought Journey on PS3 digitally will be able to play it on PS4 for free as Journey will be cross-buy to all customers.
