At this point I'll take any sector for a open world-like PvP zone. I'm assuming what you're asking for is territory control?
The developers hinted at it but it only turned out to be nothing more than a side note on their radar that's not even being discussed at the moment.
If you guys want territory control open world pvp, you'll have to make more posts asking for it. The more people that comes out of the wood work, y'know the types that aren't normally seen here like you, that asks for this, the more the developers will realize that this thing just may become a popular idea worth investing time into earlier.
So come on folks. Declare your support for territory control, open world pvp!
