Formerly known as Leipzig, GamesCom in Cologne, Germany will be host to several big events in the MMOG genre: the first public demo of Star Wars: The Old Republic, the reveal of the first Age of Conan expansion, to name a few.
Adding to the what is already sure to be an interesting event, will be the presence of Square Enix's sophomore MMOG outing: Final Fantasy XIV.
There are no solid details on what to expect out of Final Fantasy XIV at this year's GamesCom, but to be conservative I would just expect the E3 trailer to be shown again. On the other hand, you never know with Square Enix.
GamesCom will run from August 19th to August 23rd, and will take place in Cologne, Germany.
