Initially companies were said to be player run, and I'd say 99% of the player population when they were first announced back in Nov were under the assumption that they would be another form on linkshell with such things as player owned land, player owned airships/boats which would take you to special content areas. I remember thinking our crafters in our LS would each have to build parts of a great big airship/boat that would take us away like pirates to new content/quests. Speculation was that they would tackle content such as the garlean empire invasion or beastman tribe invasions etc. Then we had Yoshi get his promotion and everything was getting overhauls. This whole player run company thing was never mentioned again by SE till now. They are just confirming that we are going to get something player run/organized eventually but right now it is most likely the grand companies are organized by an NPC.
Let me preface this by saying that I think your ideas / concepts / notions of what "player-run companies" should be or could be are very intriguing and creative. That being said, the community should know that this is 100% unfounded conjecture and absolutely no one from SE has ever given one iota of substantive details about what a "player-run company" is. Because SE has no idea what they actually are, they just know that they are "still coming".
Still, I honestly do appreciate the increased communication. I'd rather hear that some feature is still in the works and that they haven't forgotten about it or scrapped it, as opposed to hearing nothing at all until a couple weeks before the patch goes live or at one of 2 or 3 yearly press releases.
But how many more empty promises, tenuous plans, indefinite timelines, and poorly thought out concepts do you expect me swallow SE? I'll trade the over-communication for real substantive content anyday. I don't care if I never hear from SE again as long as they actually deliver. All words and no actions do not make for an enjoyable gameplay experience.
SE: "We are still working on the player-run notorious chocobo jousting grand company dungeon. Additional details will be released when we figure out what the #$@* that means."
