The PlayStation 4 port of That Game Company's Journey is still on track.
Journey will arrive someday to PlayStation 4. That day is getting close though according to That Game Company.
One fan asked the developer on Twitter if they have any news as to when.
@NaughtyGods Tricky Pixels is still working on the port, and it won't be announced until it's been completed, but it's not too far off.

As you can see, no date, but at least it's not far off, whatever that means.
Sony revealed all the way back before gamescom last year that Journey is coming to PS4.
