It might not be his MK 2011 concept but it is definitely legitimate Goro art from NetherRealm Studios. The photo was taken by Hector Sanchez's sister.
NetherRealm Studios had an Open House of sorts recently and she took the picture of this epic MK Tome:

as well as the Goro pic, while attending the Open House because it appears on her photography website:

The fact that it is being presented in such a way, looks like it was old concept art NetherRealm Studios had and wanted to show off at the Open House but doesn't mean it is Goro's new look. Concept art in a game currently being developed isn't normally presented in such a grand way.
