what will be the larges pve scale endgame that is in the works already? (must know, above all things)

will pl'ing be changed/removed or made so it don't work as well past rank 50? and will full party job grinds be available like old school ffxi grinds?

these 2 are the most important to me and if i had the answers to them right now i could easily know if i'm playing this game for a long time or leaving.
