The reason why I did just subscribe to Dungeon is because I became aware of the maps as of today! This is very good idea to remake those maps (I have the old one with hex), but an update is very welcome! I also find (from the online supplement) that much focus is on Greyhawk, that is just excellent!!
The things I hope for the maps are:
-NO HEXES please! The maps are already crowded enough!
-Roads: major and not-so major roads between town-city-metropolis
-Downloadable from online supplement so it can be used (small parts that I can customize) for my games
-Important location from publiashed module (from what I read above, it is already done - good).
