Legend
It depends on how far south and east they go. If they go as far as Ed's original maps - southernmost latitude being at Nimbral and the very southernmost coast of Faerûn between Halruaa and Dambrath, easternmost longitude at the Howling Gap and the eastern limits of Ulgarth, it will just miss Zakhara at the southeast corner. If they go much further, then, yes, it will clip parts of that continent. But even then, it's not going to show much of significance (the area in question is unsettled barren coastline) unless they greatly expand the map's reach beyond Faerûn proper. Once a hypothetical map gets fairly significantly south of Nimbral, then places like the Pearl Bay and the Corsair Domains would start showing up. I personally don't think they'll go much beyond the original Ed maps, if they even go that far (hence my wanting to know if the south coast is on the map).
Ed's original map went all the way to Semphar and the southern most coast of Faerun.
