Not sure what the two new upcoming races are.
1. Torians - New ability "Aquatic"- race comes from a long history of being able to live in water - can colonize some water tiles near land increasing the quality of planets with water.
Being an "Aquatic" race they can place Markets, Research and other buildings (except manufacturing?) on water tiles. One race cannot be "Synthetic" and "Aquatic" at the same time.
Advantages: high population growth and high research.
2. New Avian race - superior pilots and a militaristic race
