I understand that it just seems (for me)little. For example fifa as had at least a campaign + 1-3 new/reworked mechanics + FUT support + new visual stuff (like stadiums/leagues/managers) every year for the last 4-5 years. It seems an extremely hard task to do every year without crunch even if you had like 2000 employees. Again i'm no engeneer but wouldn't the code be extremely hard to understand after doing this? wouldn't there be a crunch pressure since you already know the game is releasing this year? for example let's image they are doing something and frostbite tools don't allow it; can they afford to wait for tools, Is it necessary to make the tools alongside the features?
Also despite having all those employees Fifa manager mode is heavily stagnant. I doubt that mode would linger behind if the devs hadn't the year release date.
Again maybe i'm wrong but for me 2000 employees sound very little for a game that releases every year.

Planning, it is called planning...
It is not like FIFA begun to build their first Frostbite release after their last Ignite - in one year...
This is how
I think they do it.
* A tech group tries to make a quick port an old game, like 2010, to Frostbite, notices what is missing.
* A full port with implementation of all needed features is planned, X years...
* It is noted that Frostbite could support Single player story mode, a writer is hired
* Porting and writing of story make take several years, during this time FIFA releases as normal; roster updates, hoping that PES do not release story mode
* Port a newer one like 2014, to verify that everything works - now the engine is ready
* Changes in preproduction, like rescanning of stadions for PBR
* Scanning of actors for story
* Scanning of players, roster update
* Test, test, test
* Rescan players and stadions when needed
* FIFA 17 is released, minimal new features
* Start to add stuff
* Scan, scan, scan
* Test, test, test
* FIFA 18
I assume any FIFA release to take two maybe three years from first planning "what do we want to change" to release, adding Frostbite might easily have doubled that - but first years the team to do that would be small (those not in it still had to release FIFA yearly). This is also how I expect most AAA releases are done, most software in fact!
