Square Enix recently added their press conference to the E3 2009 schedule, but what will they reveal? We're likely to see more on Final Fantasy XIII, but you can bet Square Enix isn't stopping there.

I suppose we'll see solid information on XIII, XIV, an American release date for Dragon Quest IX and maybe, if we're lucky, some Versus XIII.
Besides, you know, Kingdom Hearts Wii.
