What's the benefit of them stretching out the game for that long? This isn't a subscription based game.
To keep a healthy playing userbase. Doing so can keep people talking about the game, and help it have legs.
If it was just game now + new big content patch X months from now, then people would stop playing this game well before the patch comes out and move on to other things.
Trickling out content keeps people interested and invested, if done well.
