^Yeah, it does look very strange. Swarm/X-Flight don't have them on their zero-G rolls either. I know they're smaller, but this certainly does look very new for B&M.
I'm more and more intrigued by the layout of this coaster the more I see of it. I'm guessing a large zero-G/corkscrew element, then some sort of giant version of the weird roll found on Flug der Damonen. With a little less extreme of a turnaround on the exit.
Then it looks like it's heading up towards some sort of MCBR.
I know it was only concept art, but this section does seem to differ from the artwork posted on the first page.
