Best Buy has listed "U4" as a game for the PS4 with no other than Sony as the publisher. You don't have to be a genious to figure out what it stands for and you can already pre-order it.
We already know that Naughty Dog has a team that is working on a game for the PS4. The three previous titles that ND released were all announced on Spikes Video Game Awards and considering TLOUs insane praise: one has to assume that its going to get a lot of attention on the VGAs which makes it rather possible that they might even reveal UC4 there in December.
So what will the game be about?
Let me just shortly say that HipHopGamer has made a video where he says he has "heard" that UC4 will be about Sir Francis Drake and some journey in the ocean. Take this with a huge grain of salt.

But to continue...
One can find a ship steering wheel in the museum part of The Last of Us. An almost identical can be found in Uncharted 3's museum and Drake can even interact with it and move it left and right. A user on GAF has pulled this from Wiki after seeing the steering wheel in TLOU:
"The city of Cartagena de Indias -
Cartagena of Indies, in the eighteenth century, was a large and rich city of over 10,000 people. It was the capital of the province of Cartagena and the main town had significant fortifications that had been recently repaired, increased and improved with outlying forts, batteries and works. Its harbor was considered one of the finest in the world and it served the galleons of the commercial fleet, Galeones a Tierra Firme y Perú, that annually conveyed through Havana to Spain the immense revenues of gold and silver from New Granada and Peru.
Founded by Pedro Heredia in 1533, it had been the target of conquest in the past and was captured by the English, under Francis Drake, in 1585"
This could very well be true seeming as Uncharted 3 had a few chapters that had a large focus on the ocean and water (not to mention Cartagena). Naughty Dog even simulated an entire ocean. For all of you that played Uncharted 3: You probably felt that the chapter in particular felt a bit like a filler and aside from it being one of the best levels in terms of design and visuals in my opinion: It didn't really do much for the actual story aside from show how far Drake is to go from Sully (which is already shown several times, take the Desert for an example).
So could this have been a way for ND to start early on Uncharted 4? We also know that ND will be using the same yet upgraded engine for next generation so the possibility is there.
Lastly, I am sure many of you remember the two images that were discovered during a making of video in The Last of Us. Now that the game has been released and I have finished it: I can't for the life of me see any place where any characters are dressed in the same way as the image shows. With everything I have said before now => These images could very well be Uncharted 4 concept arts.
In the end this is all mere speculation. The thought of another Uncharted in next gen makes me really friggin happy. I really hope we hear something soon.
