As with pretty much every rumour on the internet, take this one with a gain of salt, but if a leaked set of internal emails over at EA are to be believed, A Way Out won't be coming to the PlayStation 4 until 2019.
The leaked memo describes the co-operative experience as "one of the most anticipated games of 2019". It then goes on to discuss possible media opportunities, as well as a road map to release:
It was assumed that A Way Out would release next year in 2018, and so this is a bit of a disappointment if true. Were you excited to check out A Way Out next year? Don't shoot the messenger in the comments below.
