Really interesting story.
Meanwhile, in the Bridle Path, it looks like 5 High Point Road is now for sale. $7M essentially for the land.

Apparently the current owner of this lot encountered some similar neighborly issues when he wanted to cut down 60 mature trees on the lot and build a 30,000 sq.ft. home that was 2.5x higher than zoning allowed for. The story came out in 2008 but it sounds like the current owner bought sometime between 2003 and 2008. The property is now being sold nearly 10 years later, so it seems like the owner has tired of the battle, has conceded to the neighbors and is walking away from it all.
