Although the two actors have no costume but are rather wearing motion-capture gear for CGI effects afterwards, they are holding spears which are identical in design to that of Corvus Glaive and Supergiant from Infinity.
Actor Terry Notary was recently cast in Avengers: Infinity War, and although he didn't reveal his role he did say that he's working with Josh Brolin as Thanos's "right hand bad guy."
In comic books, Corvus Glaive eventually rebelled against Thanos to side with his son, Thane.
Avengers: Infinity War is scheduled to be released May 4, 2018.
