I think its great that someone is trying to do an "Upgrade" of Wilderness Survival from scratch. Wilderness Survival doesn't seem to get updated anymore and its lacking alot of features and fixes so the idea that someone is revamping the gameplay of that map is awesome. Hopefully this map will also increase the hosting of itself and wilderness survival on Bnet as currently finding it is next to impossible. Many of the features listed are going to add a polish to this map that Wilderness Survival always seemed to lack, best of luck!
EDIT: Also constructive participation of dead players is a great feature, as I for one always hated when dead players just sat around pinging the map or revealing to their team what other players are doing or where they are. Also those screenshots of the terrain and game interface are very nice and the terrain seems very well done and thought through.
