Take this with a grain of salt, because I myself have reservations, but a Swiss online retailer has listed a product page for the rumored Uncharted trilogy for PlayStation 4.
Spotted by Reddit user Kayyam, the listing includes mocked-up PS4 box art for the game, a release date, and a price. Now there's a few things that are shady about the listing. For one, the box art is clearly using fan made art. The September 30th release date is also a Wednesday which is odd considering games typically release in Europe on Friday.
Still, though, there's something interesting about the listing (which has since been removed). Although Naughty Dog has denied claims that it's working on an Uncharted trilogy, we've seen hints over the past year that suggest it's something that could come to PS4.
About a year ago, Scott Rohde, PlayStation Software Product Development Head for Sony Worldwide Studios America, tweeted an image of a giant Uncharted 3: Drake's Deception box alongside a PlayStation 4 controller. So far it's only led to speculation that either Uncharted 3 will be remastered for PS4 on its own, or that Sony is looking to bring the entire Uncharted trilogy to PS4. We've yet to hear any formal since, but Sonys Shuhei Yoshida previously described the franchise as a "good candidate" for a PS4 remaster.
