The concept art in the second picture is clearly a human - looks similar to the Cerberus troopers.

However there is also no way this game will not feature humans as playable - to do otherwise will not generate mass market appeal and bring in new players, something severely needed after the fanbase's reaction to ME3's ending (which I will not discuss - I have said my piece time and time again about it).

From what little there is I am intrigued, and I will be paying close attention to Dragon Age Inquisition for a good look at any gameplay or engine advances that might cross over into the new Mass Effect.
