@OP, sure there could more out there, and hopefully there will be - there's a lot of permit locked systems/regions, so I'm holding on to that as a hopefully brighter future. As for exploration being ruined, nah. I landed at BP later than the fleet, but before the deadline, and then made a hard right and am still some 50kly from Sol, somewhere in The Veils now(?) still enjoying the moderate diversity of most systems, the rare visually spectacular sights, and still using the FSS - not for every system, but anything with ELW, WW, lots of GG, massive body counts, or even if I'm just bored of jumping.
PS well done starting another boo exploration thread, what did it take, three pages before the magnificent five rode in to take over and resume bleating their dead horse.
