They did say there taking it from Tiger woods and in that game you could morph many parts of the face... I know in the WWE Smackdown Series (Shut your mouth, and Here comes the pain) you could morph many parts of the body the face (eyes, mouth, nose, cheecks, chin) and the body (arms, legs, chest etc..) So If EA could atlast let you morph the face that would be awesome.
But in regards of the DNA, I know in The Smackdown series also
were going to use a simular system but dropped it because of it not working so well, but of course creating a wrestler had alot more stuff to take in account (cloths etc..) but with Fifia its more like faces and body shape. So I think if they could pull it off it would be pretty sweet, and deff something that I havent really seen in anyother game yet so thats deff a plus and sometihng revolutionary in my opinion, with DNA you will be able t create your favorite player in no time...
