Right now, the Zoners and Guild Core are staring at each other menacingly while waving around large <strike>penises</strike> warships, everything else seems to be business as usual.
As for 4.86... well, the Gallic Royal Navy and the Zoners haven't really been getting along too well (read: they shoot each other on sight) and the GRN is going into the Taus in 4.86. There are Zoner bases in the Taus. Do the math.
