Checked out Metroid Prime 4 on IMDB and ran across these photos.  Does anyone know where they came from and are they just fan art or past game drawings?  The first picture in particular is intriguing.

I have a hard time believing these are true.

The first one is some random mockup that I'm not even sure was supposed to be related to Metroid.
Second one is some random fanart.
Third one is Ridley's render from Prime 3.
Fourth one, no idea.

Thanks.  I figured they weren't real since I hadn't seen them yet or didn't recognize them.  I'd imagine any sort of Metroid Prime 4 imagery at this point would blow up parts of the internet and you wouldn't be able to miss them.

Fourth one is some creature on the Planet Phaaze that latches onto you with his long tongue when you're jumping down a chasm.

IMDb content can be edited.

None of that stuff is officially from MP4.

Mostly fan art, you can tell because if it was official Samus' outfit will be a lot more colorful... also probably have her in a action pose of some sort.

The first image was taken from the Nintendo On video, a mockup of Nintendo Revolution which was the codename for Wii.

The scene for the image is at 6:05.

Eh, likely fakes.
