The trend in current military development is Enhancements to existing types of weapons and units, which leads me to suspect that the Technological Upgrades that the GDR has in Gathering Storm might be extended to other units in the game: potentially the entire game, but certainly in the late-game. After all, a major change in old-fashioned 'ground pounder' infantry has been that in the past 20 years they have added body armor, enhanced vision devices, GPS location and satellite communications down to the lowest tactical level. Personal Drones, Drone Swarms, Nano-systems, Exo-skeletal enhancements, wearable electronic and other types of high-tech camouflage/'Stealth' systems, have all been experimented with already. Now imagine the enhancements that could be hung on larger 'carriers' like armored vehicles, helicopters, aircraft, et al. By definition it is almost impossible to predict a brand new system or weapons system, but it is not hard to see the kind of changes to Existing Systems that are probably right around the corner.
