I don't think people will ever party like they did in FFXI, not in this game. You could, perhaps, form a small group with a friend or two and do rather well. But soloing is easy and a powerlevel is even easier; and aside form those, it's mostly levequests and "raids." When SE adds cross-server auto-grouping for raids after 2.0, though, that will likely spell the end of whatever parties there were, as everyone will probably just stand around waiting for the system to make things work for them.
For better or for worse (opinions will vary greatly on this matter, so I'll keep out of it), 2.0 will be using much more of a WoW architecture than an FFXI one.
