SCEA has announced that Gravity Rush Remastered is digital only in the NA region. EU, Asia, and Japan will be receiving a retail release.
On the bright side, PS4 is region free, so import away! Both EU and Asia version will contain English subtitles (no such thing as English dub as the game has a fictional language.) Disappointingly, SCEA seems to be following a trend of releasing Japan Studio games as digital only in NA.
