It doesn't mean we won't see ANY improvements. In just mean we're not likely to see a breakthrough that'll make it a viable alternative display for general devices.
Btw, lcd has also pretty much reached its limit too. That's why there is a lot of excitement around OLED, which people are hoping will supplant lcd.

Would not each of the capsules in the eInk screen be a pixel (picture element)? Just to make it more fun, an eInk screen needs 25% to 33% of the elements that an LCD screen needs (one capsule per pixel vs. the 3-4 elements needed for red, green, blue and in some cases, yellow for the LCD pixel) for the same DPI. So an 300dpi eInk screen would need to address 90,000 elements per square inch while an equivalent LCD/OLED screen would need to address at least 270,000 elements.
On the other hand, since eInk uses physical movement of the pigments, I can't see the speed of an eInk screen ever getting close to that of OLED screens. Milliseconds vs. microseconds.
