It would be a nice lens if it wasn't for the fish eye part.

Personally, I've never understood people's interest in fish eye lenses...
As gold fishes maybe, but as humans? ;-)

Hmmm? The fish eye part is needed for its purpose. Without the "fish eye part" the lens has no reason to be? The resulting output gets processed, you don't have fisheye video as end result. You have VR content as output.

VR has nothing to do with being fisheye or not.
If you look at the video excerpts from the link you posted, you'll see they are fisheyed.
The same lens but corrected for distortion would have been a much more interesting offering.

You do not appear to get the concept.

The lens captures a wide view. This is for VR content. Not for web videos. 360 degree cameras also are not for fisheye photos or video, but to process for VR content, so you have a wide view.
Then you put a VR headset on, and can look around the wide view, which is remapped. The video of course does not show VR, now does it. It can only show the quality of the lens.

THAT is the concept, and it makes no sense at all to use "corrected lenses".

Indeed, I didn't see the motivation. I see why it could be interesting to this specific niche.
