This continues to be a closely guarded secret, with phrases like “later this year” and “holiday season” being the norm.
Now our whispers who claim to be in the know say that at least right now they are hearing that Uncharted 4 is targeted for a September 29th release in North America, followed by an October 2nd release in Europe. We heard some of a unified release on October 2nd, but right now that seems to be just talk.
Still anything could happen and the dates may change or move around depending on the development schedule. Of course this is only talk and we suspect that a final decision will not come till E3 from what we are hearing.
