The thing that's killing, is the masculinity and bone structure in the face and muscles (and of course the hair), he almost looks like a kid in the face but Russell Westbrook was the same way in the trailer and in the screenshot of Nerlens Noel... The faces are just too rounded but I'm also ready for gameplay...
The thing that neither game's dev team seems to have figured out is that players where different sized jersey. Don't get me wrong - NBA live still looks stunning (coming from a PC player with very little choice :P), but if arm holes were reasonably close to reality (even just 4 or 5 different jersey & short sizes spread across the height range) it would do a lot to bring out the body types that both companies are spending so much money on scanning for accuracy...
