A new interview with the developers of Metro: Last Light has surfaced, which suggests that the upcoming first-person shooter may well release on the PS4.
There's no official confirmation yet, as the news comes from a translated interview. However, if the website called itcchannel (who're from the Ukraine) are to be believed, it could be a rather solid deal for people who purchase the PS4 version.
Not only would the game come with boosted graphics, which would make it resemble the PC version of the game more closely, but it would also come with the original game. This is great news, as Metro 2033 skipped the PS3, instead releasing on the PC and Xbox 360.
If this did happen, it would be much later down the line. Metro: Last Light is due to release on the 17th of May, 2013 on the PS3, Xbox 360 and PC.
