Yep. But then again, it isn't as simple as that, as the applications won't simply quadruple everything. You will be able to zoom out images, for example, and they won't be quadrupled (they can be 1:1 pixel-wise).
Bit confusing, but for text work, not really much point unless you want huge quantities of tiny text on screen. Image editing will probably see benefits, but video editing will still be restricted to an interface that is the same size, meaning that you won't gain anything at all from shrinking the video on screen.
