I've read (probably on prior HN discussions about this?) that the manufacturing process still has major yield issues— when you're making small displays, you can slice around the bad pixels and not have to waste as much, but making a large display requires a huge sheet to all be perfect.
Then again, if that was really it, surely there'd be a market for people who want a 42" e-ink display and are willing to accept some proportion of bad pixels in exchange for a deep discount. Which really shouldn't matter much, particularly for applications where distance-viewing is the expectation.
