How likely are we to see a Lychguard/ Praetorian/Deathmark/Immortal refresh?

I understand destroyers and maybe some c'tan are first on the list (banana boy and daddy nightbringer) but looking at our elite infantry they definitley look slightly dated next to the new warriors.

Currently my guess is new destroyers next edition. Then elite infantry in 12 edition, was keen to see what other people thought.

Edit: oh shit i forgot the brother Trazyn. He's definitley at the top of the list
