Obviously Sasuke negs since he's still a thing in Boruto the movie, but the multiple sharnningan guy may have a bunch of MS abilities in each eye, an upgrade from danzo. But that guy is trying to steal Yhwach's look

. I feel as though the guy's MS ability is to control metallic forces in one eye and kumai snipe in the other. But the power works like the six paths of pein though, maybe he'll try to pull an orochimaru against sasuke but he'll get rinne solo glanced or something new from sasuke we haven't seen because to date, sasuke has ONLY used up to 3 Tomoe he hasn't even used EMS not to speak of the rinnegan.
I would laugh if sasuke CT's all of them though but I hope the guy gives a good match up
