The cover for Weapon X #18 has finally been released.
Gotta say, all the covers since chapter 15 have been very bad. lol
In any case, looking at this, seems OML & Warpath aren't leaving the team, like solicits would have you think. But they just both got captured by Omega Red, which is why it's just Sabretooth and The Ladies in chapters 18 - 19. Seems that roster change may not happen until the "Fresh Start."
