If this is the case, then it would seem to me that the ability to produce modular e-ink displays, where segments are individual, independent displays, would be an option.
This is most tenable for large-scale displays (e.g., wall displays), and we're already used to segmented "television walls" in which borders between individual displays is strongly evident. The trick would be for such compound devices to both match one another's display characteristics (brightness / shading / hue), and for borders to be made as undetectable as possible (several possible mechanisms suggest themselves to me as I write this).
Given the sweet spot of 8--10" displays, compound devices made of multiples of these would seem to be at least a conceptual possibility. 16x8 displays would give 32" diagonal measure, 300 dpi, and assuming 50% BOM cost might run less than the 25" Onxy BOOX Mira Pro ($1,750).
