Is rumored to be Hypermode, and not Dark Samus. In the game, you never get a real good look at her, unless you look real close, scan or pause.
Here's my comparison to this "New" Dark samus, and real dark samus...
OK, first: The Helmet: (Dark Yellow) The dark samus to the right, her helmet looks more fleshy, and darker and more evil.
Shoulder Pads: (Dark Blue) The shoulder pads on Right DS looks strangely like Metroids...
And it also looks more fleshy.
Torso: (Purple) Obviously looks sort of like tissue on the right DS. And it has sort of a different design.
Hands: (Gray) They are more like normal Samus on the left DS. But on the Right DS, they're more like claws. A lot more. And they also have the "eye" thing that's on the hand of DS in the end of MP.
Arm-Cannon: (Red) The gun on the left DS is more cone shaped. And has a weird tip thing.
However, on right DS, it's more like normal Samus's arm cannon.
Knees: (Turquoise) The knees right DS don't have Knee Blades, but on real Samus they do, and so does left DS.
Feet: (Green) Well, same as hands.
The right DS was seen in Metroid Prime, and Prime 2. So, I have to swing towards that the left DS is Hypermode Samus, and not Dark Samus redone. You decide. But all questions will be answered when the game comes out. 60 days. (Aprox)
But wait there's more! In a trailer for MP3, it shows that this is Dark Samus indeed.
Looks can kill.
