DotA 6.76c AI Map is going to be the next big thing after official map. DotA v6.76c AI will take weeks to release because of massive amount of changes from 6.75/6.76. The developer PBMN will have to sucessfully implement each and every change in a sequence to make the AI map work. When the map releases, it will support Arc Warden and Winter Wyvern AI.
But until then, we have to wait.

A Chinese DotA AI Developer DotaER has released an unofficial version of DotA 6.76c AI. It is fully compatible with v6.76c. You can enjoy this map until the official version comes out!
