CCP doesn’t need to open up Jove space for that. From a gameplay perspective, we’ve got nearly untouched planets, station interiors, ship interiors, and a whole host of other in space assets. Those locations can be for the fps / third person shooter player to explore in a more traditional way and the domain of flying around in space can be the environment for EVE Online.
CCP London has been working on a shooter that some have speculated will have more mmo features in it than dust did. So something similar destiny or warframe with probable pvp gameplay.
Personally, I think they should aim for full integration, which will actually drive EVE subs if the shooter gameplay is popular. However, I understand there can be technical constraints, which is why I offered a bit of a compromise in another suggestion that was created a bit over a year ago: Derelict First / Third Person Exploration which details a potential mission type that loads a warframe style mission from activity that happens within EVE. Obviously you don’t want either game to be wholly dependent on the other, but ideally there should be enough cross platform activity that it encourages interaction.
