FFXIVCore.com has posted leaked FFXIV information from a Japanese magazine (Famitsu) which is out tomorrow.  It's common for Famitsu to tease everyone prior to their magazines release.

Some of the information leaked is:

• Necklaces, belts, and rings, unlike XI, will be reflected graphically when equipped
• It seems as though westerners translated my comments as “everything would be seamless” but in actuality not everything from towns and the worlds will be seamless
• Seamless movement in an area equivalent to the size of a region in XI will be possible.
• You will be able to draw weapons in towns.
• Battles with enemies will take into account front/back/left/right positioning. Haven’t thought about elevation effects
• Characters will not age, however, you will be able to change your hairstyle
• Deterioration of weapons may be reflected graphically as well
