I have a feeling they'll go with a 6-man rotation of sorts (though maybe no a full-set-6 man, if that makes snese?) The Cubs have 5 guys right now who can start (though not the 5 guys who should be "the rotation" if that makes sense) in Steele, Hendricks, Wicks, Asad, and Smyly. Wicks has already a good amount of "6-man rotation" in him. Whether the Cubs go with a Glasnow, or a Bieber, or one of the Japanese arms, they'll also be somewhat of an innings-watcher. Japnese arms tend not to pitch as often/much as American arms, and Glasnow/Bieber have plenty of injury concerns. Kind of the perfect situation for a 6-man, if you ask me. So maybe someone gets a break here or there through the order, or a rest.
