Neither Journey nor The Unfinished Swan are coming to PlayStation 4.
Speculation that the pair were heading to Sony’s new console began after Sony Santa Monica’s creative director Nathan Gary tweeted pictures of Flower, Escape Plan and flOw being played on the machine. Pictures of The Unfinished Swan and Journey followed these PS3 and Vita titles.
However, Gary later clarified that this was not confirmation of a PS4 release.
Lots of people asking so I'll clarify. Was nostalgic playing the PS4 versions of the games so I busted out the PS3 to replay some others.— Nathan Gary (@Nathan_Gary) November 3, 2013
Ports of Flower, flOw, Escape Plan and PS Vita title Sound Shapes are all launching with the PS4 on November 29th.
