No "mystery" at all. The answer is simply, I suspect, that A4 eInk screens don't exist, and the manufacturing yield for them would probably make them prohibitively expensive at present.
People have been quoting around $200-ish to get the screen on a Sony Reader replaced. That screen has around a sixth the area of an A4 screen. Let's be generous and suppose that the cost is proportional to the screen area (it probably increases at a much higher ratio, in reality!). Would you pay $1200 for an A4 screen?
I'm sure that we will see A4-format devices as larger screens become cheaper to manufacture.
