Is This The Mercedes-AMG GT Black Series At The ‘Ring?

If the rumors and murmurs are to be believed, we should be seeing an all-out Mercedes-AMG GT Black Series sometime next year and this video seems to confirm it.

Thanks to the YouTuber for the footage you can see these prototypes are sporting new winglets on the front which are not part of any GT model at the moment and it looks a lot more aggressive than the already aggressive GT R.

What are your thoughts on this?
