Is there any realistic chance that we get a decent espionage tab with lots of good content like in Endless Legend, ofcourse modified heavily to fit ES2 , on the release or first patch.

Game looks very good so far but waiting for an expansion/dlc to get espionage is a moderate/big letdown for me and i am sure many others

Espionage or intrigue is basic concept that all humans and probably most of species in any universe will practice very early,imo its too important to be added later on, for a great game at least
