Some more info. I got this from the wiki page. I think it's cool that Guest characters can be playable now =)

An international version of the game, titled Final Fantasy XII International Zodiac Job System, is set to be released on August 9, 2007 in Japan as part of both Final Fantasy 20th anniversary and Ivalice Alliance campaigns. The game will include a new take on the Licence Board system, with twelve grids available instead of one, each corresponding to a different Zodiac sign and job. The battle system as a whole will also be tweaked; guest characters will now be controllable by the player, while pressing the L1 button will accelerate the game's speed. Additionally, the game will feature the English voices and the widescreen 16:9 ratio support of the North American version, as well as a bonus disc based on the one initially released with the North American version. Finally, a new mode will allow the player to hunt monsters and Espers in several series of small maps, to gain items and money.
