Fire Emblem If News Discussion: Is Both Games Worth It? (How Big/Long Each Are) + Amiibo Support, And More...
Ok i want to point out the major things so lets goooooooooo........
First things First to get this out of the Way....
★Amiibo Support: Well Nintendo Updated the Box Arts, Originally nothing was there 
★How Big Is Both Games? Because of it being split into 2 versions, does that mean we are getting ripped off? Well unless you dont think rationally, i'd sa no!
Take a look at this quote from an interview with Intelligent Systems...
"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."
We know the prologue and the first 5 chapters are the same in both games (Ch 6 is where Avatar picks his/her side), so we can look at it this way. 5/6ths of the game excluding Prologue is Roughly 26-32chapters per game. If they included it, we definitely be looking at a 30ch+ game each. For a comparison, Awakening had 27chapters (includes Prologue+Endgame)
That said with White version being more akin to FE Awakening (a map of the world/etc), im going to put a guess here.
⇒White Version will be 26-29chapters long with several side maps like awakening (Aka Grinding Chapters)
⇒Black Version will be 31-35chapters long. Much Harder Difficulty
This is to say with the third path DLC has its own story we can see another 20+ chapter game!!!
Here is more info, including DLC that looks like it literally could be a 3rd game on its own 
The Nohr campaign features diverse victory conditions, such as seizing a location, breaking through enemy lines, defending your base and maps with turn restrictions.
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.
