The smart money is betting on that the much heralded "new space" that players will be building stargates to is the Jove regions that are now probably unoccupied, or at least occupied by Sansha's and/or Sleepers.
I'm not so sure.
No, I suspect that we are seeing a purposeful and graceful expansion of current space and the Jove systems will play into that plan, but the end goal of the road we started in Rubicon is beyond Jove, beyond wormholes and the Shattered Systems. New space, real and expansive new space, is still coming.

Crystal Ball Prediction Time:
Players will find a way into Jove space, probably via wormholes, possibly with new technology to make jumps or stargates. I suspect the partially cloaked Unidentified Objects we are seeing in space from the Rhea release will play a part in getting us there eventually. In there we will start to find the components and techs we need to make the next jump to the new space which will be much larger than a couple regions. Think wormhole space big at least.
