In the ending of SupCom2, Ivan says "we are in the dawn of a new age..." The collation is fragile. If someone found out how to completely transfer consciousness from flesh to machine like in the begging of OTA, it would make sense 3 factions merge into 2, and start fighting each other again. Most living things will die, and then there will only be machines fighting each other, just like in TA.
Wouldn't it be cool for Gas Powered Games to release a game bridging the storyline of SupCom2 and OTA?
