This is really a nail in the coffin about Space Marines getting a new scale of miniatures.
There are quite a few sources here on Faeit 212, and one of the strongest has chimed in to help us decipher the Real Scale Marine that has been making the rounds. So yes, I believe what this source is saying without a doubt.

The image you have circulating of the dual wielding marine is a kitbash fake.
It was discussion of the image that spawned the first rumor: "I saw it, it had sigmarite-like legs, a longer bolter" etc and not the other way around. People seem to think the first rumors gained validity by the model that followed, but it's the other way around.
The image you have been circulating is not a legitimate product.
There are new marine kits coming. There are always new marine kits coming. At this time there is no intention to change the scale of space marines, due to the importance of cross-compatibility of bits.
