Several weeks ago we looked at the possibility of Naughty Dog either releasing a sequel to The Last of Us, or Uncharted 4 for the PS4. We decided that the former was out of the question for now, and fans desired the latter. It is for this reason why we doubt the credibility of the Last of Us 2 pre-order going live.
It seems a Swedish website in all its wisdom has listed The Last of Us 2 for the PlayStation 4, although they have not offered a release date. Seeing something like this made us have to do a double take, but it was there plain as day.
The website has not had a very good track record with pre-order listings in the past, but this is not the reason why we doubt this one. It is Naughty Dog themself, as they have already said they have no such plan to work on a sequel to The Last of Us just yet.
We know that a sequel would be welcome for the game, and to see what Naughty Dog is capable of on the PS4, but it is far too soon for a second version.
If there was to be a sequel, then we would not expect The Last of Us 2 release date until the end of 2014 at the earliest.
