At least according to EA Canada's senior producer Jason DeLong when he says "I think that we’re going to start to see – maybe not in the next year, but in the near future – games go down the route of smaller up-front experiences and lower prices at the beginning..." and then continues "....and then the ability to extend the game through episodic material or future feature material. I think that’s a direction we’re probably heading in."
Personally i think EA is taking the next step in DLC scams (or shooting some steroids into Ubisoft's current one), chopping up pieces from the whole game to sell them as DLC hence making games shorter while looking like they are actually caring for customers by lowering the prices mildly. You know what i think Mr. DeLong? you and EA can go get ass raped by a donkey.
