Its content for people that you know... might not have played FFXIV before 1.0 and gotten all there classes lvl 50? Mid-game content is ridiculously sparse in 1.0, basically all the content is at the higher level with a couple milestone quests here and there sprinkled in the middle and one single instanced dungeon, they stated they wanted to rectify this. Not to mention they already confirmed dungeon content is level locked and people would sync down to the level of the dungeon so they always remain at least somewhat challenging. Can't just use a lvl 50 and solo through the dungeon since it will pair you down to the appropriate level.
Edit: Holy Hell at the official forums... I stayed out of those grass threads but now some of the usual suspects are reverting the PS3 UI thread into a graphics pissing match between MMOs >< The nice bit of info we got inside it though is that there is new interviews from Dengeki Playstation and Famitsu inside the magazines on top of the two already released from gamewatch and gamer. Also someone probably guessed what the new dungeon is likely going to be;
Ipsen's Castle from FFIX.
