Don't think Usyk gonna get a Wilder fight anytime soon I guess it's more so to get his name out there to more fans in the US.
Wilder has Ortiz and Fury lined up, and if he gets past Fury (I don't think he will) possibly Ruiz too if Ruiz beats Joshua. I can see maybe a Kownacki sliding in there between those fights as he is a HW PBC fighter who they been building for some months now.
Usyk is with Matchroom who are currently in the worst relatisonship with PBC out of all other promoters and he can't expect to get a helping hand from the WBC either, they pretty obviously side with Haymon (and sometimes Oscar), not as obviously as the WBO with Arum and Warren but still it's quite visible.
