From the info we have we have at least another 3 naval units in modern era in BtS, and we have now trade routes pillageable. What will be the differences between modern era era naval warfare in Civ4 and BtS?Do you think units will have same stats or there will be a great overhaul also of units available in Civ4? Considering that now we have at least 7 warships instead of 4 in modern era, i expect a major overhaul of Battleships and Destroyers.Battleships perhaps could get an added option to bombard land improvments.It would be also interesting to know what will be the usefulness of Stealth Destroyer and Missile Cruiser (AEGIS?).Is also in your opinion Attack Submarine a Nuclear Submarine or a Submarine with better stats? About Destroyer and Stealth Destroyer what will be the differences?
