The list was posted on Sony's official Gamescom.4theplayers.de site, but pulled a few hours later. Of course, once it's online it's bound to be replicated and, sure enough, the list was posted on NeoGAF before it could be pulled.
While Sony is yet to officially announce a PlayStation 4 release for either title, The Unfinished Swan recently popped up in a ratings board listing for PlayStation 4 and PSVita.
Meanwhile, Sony is also expected to revisit PlayStation 3 adventure Until Dawn. It was previously shown off in 2012 working with PlayStation Move. Sony said earlier this year that Until Dawn would be a “good fit” for its Project Morpheus headset.
Sony’s Gamescom conference will take place on August 12th. We should hear details about Journey and The Unfinished Swan, while titles such as Surgeon Simulator, Alien: Isolation, CounterSpy, The Order: 1886, and Project Cars will also make an appearance of some sort.
