I picked up a copy of the new official map at the I-68 welcome center a couple weeks ago; it appears to show 52 on the new alignment. US 48 appears for the first time, shown as complete up to WV 42. It does not show the proposed route between there and Kerens, though.
This map uses different fonts from previous editions and shows physical relief. Overall, it seems to be a nicer looking map, and the city insets on the back are easier to read. However, I think that the font they used for the smallest towns is too small and doesn't show up well against the gray relief.
I also noticed a few errors, which surprised me. In Wyoming County, the road between Oceana and Pineville is marked WV 85 where it should be WV 10. Corridor H is shown as a 2-lane highway on the Elkins bypass section of the route. There are two WV 27s with no ALT indication for the alternate one (ALT 27 needs a different number, IMHO). PA 281 ends at the state line and becomes MD 42 - it should become WV 26. There is no "closed in winter" notation for WV 150 like there used to be.
Speaking of WV 150, it looks like the cover photo was taken somewhere along its length.
