RUMOR: Rise of the Tomb Raider PS4 version could be developed by Avalanche Studios

There was a couple images leaked on a website called NerdLeaks, that potentially leaked that Avalanche Studios is developing the PS4 version of the new Tomb Raider.
Here are the pictures themselves.

Rise of the Tomb Raider is being published by Square Enix, and it is known that Avalanche Studios has worked with them before. The Xbox 360 version of Rise of the Tomb Raider has also been made by a different studio called Nixxes Software, so it wouldn’t be surprising that the PS4 version will be made by another company.
