Fire Emblem If - multiple storyline paths and DLC information

Japanese publication 4Gamer has posted a new interview with staff at Nintendo and Intelligent Systems regarding Fire Emblem if, discussing structure of the game and its multiple storylines. Seems like the western fanbase wasn't the only one confused about the format of this game.

The following quote is translated information by Serenes Forest, the Fire Emblem series fansite/forum. (They're pretty cool, check them out). Sounds like the Nohr path will have more varied mission objectives - perhaps more similar to the ones found in Path of Radiance and Radiant Dawn - as well as a higher level of difficulty in general. 

We don't know specifically how path availability will work for for the localized release of the game at this point. You can review the information and media from the last Nintendo Direct presentation here.

Some key details:

• The Nohr campaign features diverse victory conditions, such as seize, break through, defend base and maps with turn restrictions.
• Up to Chapter 5, the game is exactly the same, but the rest of the game–5/6ths of the game–follows a completely different story depending on your campaign choice.
• The concept of choice was heavily inspired by the player’s choice between Arran and Samson in the first game, Dark Dragon and Sword of Light.
• Players who purchase the download version can play up to Chapter 5, but then must download the Hoshido or Nohr campaign to continue–the first campaign can be downloaded for free.
• The third campaign (DLC) is roughly halfway between Hoshido and Nohr in difficulty. You can also adjust the difficulty partway through the game.
