ABC Warriors probably won't be complete either - I reckon we'll get up to the end of Volgan War.
Interesting. I've been doing my own speculation offline and I thought we might be able to squeeze a bit more in than that. My guesswork:
Vol 3 (194)
Hellbringer pt 2 (48)
RoadKill (6)
The Third Element (24)
The Clone Cowboys (18)
The Tripods (18)
The Zero Option (18)
Assault On The Red House (18)
Shadow Warriors 1 (44)
Vol 4 (166)
Shadow Warriors 2 (44)
Shadow Warriors 3 (60)
Volgan War 1 (62)
Vol 5 (208)
Volgan War 2 (64)
Volgan War 3 (72)
Volgan War 4 (72)
Vol 6 (236)
Retun To Earth (74)
Return To Mars (79)
Return To Ro-busters (83)
Admittedly those are mostly pushing the top end in terms of page counts but all of them are within the range we've already seen in the MC and UC.
Reorganising such that Vol 4 is all of Shadow Warriors and 5 & 6 split The Volgan War material between them leaves us with some quite slim vols (vol 3 154, vol 4 148, vol 5 126, vol 6 144). Page counts that low are outside the range of what we've previously seen in the collection, although given the above conversation they would be pretty standard for some of the other collections.
Am I missing something?
