Hidden Star Systems

Hello there! One of the new features in ES2 - far distant stars which are not connected to other stars by warp lanes and can be discovered only by probes, techs or cultural influense. I suggest to expand this nice idea by adding new hidden systems with highly increased chances of spawning wonders (if they even will be in game) and rare lategame strategic and luxury resourses on them not only in edges of galaxy but right in the middle/centre of map. These systems stays invisible in early game, even for probes. How they can be revealed? By new techs in later eras or maybe by some random events. What the point of this? Imagine: You`re in a cold war with that damn nasty sophon empire hunting for so much needed ionic crystals (insert your favourite luxury here) which grows only on border planets of two empires. Battles in neutral space, struggle for every outpost.. And at last you researching 5xDimensional Deepspace scanner technology  (or something sort of) and realize that untouched virgin planet full of this crystals lies right below your enemy`s territory... 

I`m pretty sure it will add some more competition in game ;-)
