I am obsessed with these chronology-based collections as well, so here are my predictions for volumes 9-11:
Volume 9 (pre-Dim X stuff)
- TMNT #67-72
- Universe #9-15 + 19-20 (Bobby confirmed, that this arc takes place before Space adventures)
- Usagi Yojimbo
Volume 10 (Trial of Krang)
- FCBD 2017
- TMNT #73-75
- Dimension X #1-5
- Ghostbusters II #1-5
Volume 11* (Invasion of Triceratons + Aftermath)
- TMNT #76-84
- Universe #16-18 + 21-22
* updating...
Now I hope that they will arrange all back-ups in the correct order
