I've been thinking about the new areas Stargates will open up in the future. I find it quite exciting!
http://www.vg247.com/2013/11/18/eve-rubicon-sets-up-ccps-greatest-mystery-yet-interviewI shall speculate some:
1) Star gate will open to one new star system. New Eden side will have a gate. New star system side will be a permanent wormhole as long as the New Eden gate is open. It is possibly a new technology that does not require a star gate on the other side.
2) Colonists will be able to build a new star gate in the new system to connect to another new system.
3) Star gates will possibly be permanent installations like Outposts, but have systems that can be attacked and disabled as well thereby shutting down the gate until it can be repaired. Or star gates can be destroyed thereby trapping colonists on the other side just like New Eden was originally. Pop your pod to clone back or what not. Or it will be like an outpost with facilities and docking that can be damaged, but the gate will forever remain open.
4) Systems will be randomly generated with a big pool of possible elements. Some systems will be great and others will be so-so. Or as star gates are brought on line, CCP will connect the gates with systems they build.
5) The Tech had to come from somewhere, so the pirate factions possibly discovered it from the 4 ancient civs like sleepers etc. Or the pirates developed it, but I kind of doubt it.
6) Alliances in null sec will be the only groups that build new star gates. As it will require a huge amount of resources, team work, and skilled pilots. Everyone else will simply be cut off by the existing bottle necks.
7) New star systems will give the feeling of an infinite universe as long as you can keep building star gates to new systems. But with the star gate system it is still a finite box in a way. You can't just kick on your warp drive and take off into the unknown. This is a way to expand the box with great possibilities. Ugh.. feeling claustrophobic... our world is a box as is our solar system. The galaxy is a box. The universe is really just a big box. haha
8) Whatever happens I am excited to see what is found when the new star gates open.
