The War of the Magi, between Nym and Amdapor, lasted much less than one thousand years.
If they introduce newly revealed areas before the ones we have been waiting for since 2010: Sharlayan, Ala Mhigo and Ishgard (which by the way has been at war with dragons since approx. 6AE 500, or ~1000 years ago), I'm going to be really, really disappointed.
