That's actually a new 2D Zoom-In view available as of Middle East 2.0 engine, there. It is 50% larger than the Zoom-In view of the Middle East 1.x, which is now called 2D Normal view. Right click the image to open in a new tab to see it in actual size.
I am really liking the new Zoom-In views both for 3D and 2D, so much larger, they bring the tactical feel back to CS in many ways, as displays and screen resolutions have gotten bigger and bigger. With them, you can really concentrate at Coy level tasks again, as that is what you see in the display, like with the EF screenshot.
