A now-removed retail listing has suggested that Square Enix is to give Tomb Raider a next-gen makeover.
CVG reports that Amazon Italy was previously carrying a listing for Tomb Raider: The Definitive Edition on PS4. It includes the original game and all of its post-release DLC.
Also listed was a release for the game on an unknown platform”, pointing to a possible release on Xbox One.
The PC version of Tomb Raider is already an excellent looking game with visuals far beyond what was seen on PS3 and Xbox 360, so it's easy to imagine the game significantly upping its visual flourish on PS4 and Xbox One.
