At this point, the graphics card (and also the power use) becomes the limiting factor. Until graphics cards get a LOT smaller and more power-efficient, you'll probably end up trading off between resolution and refresh rate, since no mobile graphics card will be able to do high-rez AND high-refresh at the same time.

Of course, by high-refresh, I mean video speeds. Once e-ink itself becomes faster, even refreshing a high-resolution screen once should be pretty much instantaneous to the human eye...

I believe this to be an extreme requirement and not needed by most users. If you try and read 4 pt fonts then it could be important.
