You'll be happy to know that Nintendo is comfortable enough with the American audience's familiarity with Warring States Era Japanese history to not go the Sengoku Basara/Devil Kings route of radically localizing Pokémon + Nobunaga's Ambition. Beyond renaming it Pokémon Conquest, the latest screenshots suggest that the changes are minor.
Pokémon Conquest will be released in North America on June 18, 2012.

From the press release:
Following last month's announcement of Pokémon Conquest, Nintendo has revealed even more details about the new features available in the game, which launches for the Nintendo DS family of systems on June 18. Players can look forward to exploring the Ransei region and interacting with Pokémon in an entirely new way as they take on the role of a young Warlord who is linked with a Pokémon. Together they must set out to recruit Warrior allies to strengthen their growing kingdom. Developed by TECMO KOEI GAMES Co., Ltd., the game can also be played on the Nintendo 3DS system in 2D mode.
New information includes the following:
Story: To save the Ransei region from Nobunaga, a powerful Warlord who is trying to take over Ransei, players must conquer different kingdoms to strengthen and grow their own kingdom. There are 17 kingdoms in total to conquer. Conquering all 17 kingdoms and ultimately uniting the kingdom will awaken the Legendary Pokémon and save the land from destruction. Story mode is organized by episodes. Players unlock episodes as they progress and each episode features a different playable Warlord and victory conditions.
Army Mechanics: Players can grow their army by recruiting defeated Warlords and their Pokémon. After a kingdom is conquered, players will also have access to the kingdom facilities such as training grounds, shops to buy items and mines for money. Players can also strengthen their army by linking with Pokémon. Warlords can have various linked Pokémon and switch between them before battle to strategically prepare for the type of battle they are about to engage in.
Battle Mechanics: Players will encounter a wide range of battlefields as they progress through the game. Each of the 17 kingdoms has a different type-themed battlefield. For example, in the fire-themed kingdom of Ignis, players can battle around lava flows, lava beds and fire spouts. Strategically using water-type Pokémon to navigate through this battlefield will help players conquer this kingdom. Additionally, players can use the kingdom training grounds to train their army or find wild Pokémon and link with them. After battling with a Warlord, the game automatically registers them. Using the built-in local wireless features of Nintendo DS, players can use their registered armies to battle with friends who also own the game.
Warlords and Pokémon: Each Warlord has a special ability that can change the tide of battle. For example, Warlord Oichi has the ability to heal all the Pokémon in a player's army. Also, like Pokémon, Warlords have types that will determine how well they link to particular Pokémon. Some Warlords will have the ability to choose from and link with several different kinds of Pokémon.
