After much doubt over whether a game based on 16th century Japan would be worth an international release, it's finally been confirmed! June 18 is the date in North America (smack in the middle of the TSG Pokémon marathon at that), and the title is much less of a mouthful as well: Pokémon Conquest. Looking forward to it!
Oh, and the official site confirms that they're not touching warlord/warrior names, either. Good.
