Where does SW battlefront slot in the overall plan?
Dunno, I suspect this was supposed to be DICE's next game after battlefield 4. BF3 and BF4 were already very similar so I don't think they'd have gotten away with a battlefield 5 so soon after 4. But if its a new Star Wars battlefront game that's not a battlefield game ...
It's due in 2015 apparently

But EA will likely be wanting a slice of the battlefield pie from another battlefield game next year but this time from a different developer and using a new spin off brand thats based on battlefield but not quite battlefield, like Bad Company. My bet however is that it won't be Bad Company 3 it will be something completely new and will fill the EA coffers until Battlefront arrives from DICE in 2015. I wouldn't be surprised if this has already been decided, and somebody is already working on a game for autumn next year, but the rumours are coming about from people hinting that something like this is coming.
So to cut a long story short
2014 : A "battlefield game" from another studio, but not battlefield 5 or bad company 3. Something new
2015 : Star wars battlefront from DICE
2015 : A battlefile game from another studio 2. a sequel to the 2014 game
2016 : Battlefield 5, or whatever the next game that DICE works on is called.
Are they not going to be releasing any more of the bad company series? Though tbf they are a bit too similair to bf.
Nope. They binned the franchise (again)

They are looking for something to replace it with, which is where all the rumors are coming from.
