Here is my guess, based on recent history of the FFG X-wing product pipeline.
Right now we have 5 items in the pipeline. A good guess (based on historic graph) will say we will see a similar total number of items incoming in October, and a single awaited item bringing us through the Feb-Mar doldrums.
We will see the C-ROC leave the pipeline on June 8, and the Wave 11 ships in August or so, leaving only Guns for Hire (looking at an early Dec release, probably).
We can expect a "2nd day of GenCon" announcement for a 4 ship Wave 12 (SWX67-70, announced Aug 8), followed by a 2 ship announcment of The Last Jedi tie-ins ~100 days before the movie (announced Sept. 6 or so). These ships (SWX71 & 72) will "join" Wave 12, but will be released on Dec. 15, while the rest of the wave waits until late Feb 2018.
To tide us over during the bleak times of ~Feb-March, where classically we live on a single unreleased SKU, we could have a nice SWX74 Rebel Veterans pack announced on Dec 14 (for a mid-June release).
As for Wave 12, why not complete my prediction:
SWX67: large base Imperial (Krennic's shuttle)
SWX68: small base Imperial (TIE Reaper)
SWX69: small base Rebel (N-1)
SWX70: small base Scum (Mining Guild TIE)
SWX71: Resistance A-wing
SWX72: Kylo Ren TIE
and
SWX74: X- and Y-wing re-paints with dual Rogue flavor (Rogue One and Rogue Squadron).
