huh. we probably are not gonna see the map for console anytime soon. UNLESS there keeping it a secret and it will be implemented with console maintenance! i know it wont happen, but i can hope on the optimistic side.
Wyverns are seen on several maps, including the wyverns from scorched earth in locations like ragnarok. ice wyverns are just a new type, and from popularity it just makes sense to see them in this map.
