There's a lot of room for great elaborations on established genres, maybe even new sub-subgenres (i.e. a new subgenre of black metal or something), but not wholly new subgenres like what death metal and black metal were.
Part of the problem with your question is that genre evolution can only be observed reliably in hindsight. If a new major genre is being made, you won't recognize it, and if it has been made, it is already in the past. Also, one band can start a genre, but that genre won't exist unless other bands pick up on it and develop it.
Ultimately, genres are secondary to songwriting. It's not about what colors of paint you use, but what you paint with them.

I see the first album of theirs is metallic noise stuff, that could be cool. People combining noise with metal is nothing new though, and the often formless nature of noise music detracts from metal's focus on riffs and arrangements, so metalnoise is stuck as a niche fusion genre, and won't become an indivisible and essential pillar of metal like trad, thrash, black, or death metal.
The EDM sporkcore of Death Rave has more red flags than a Soviet parade, shan't listen to that.
