This is not going to happen. The game would have to be completely unplayable for them to basically start over from scratch. They didn't even do that after 1.0. They are going to continue to make improvements while the games operates, which will take time but is their best financial option. They would lose so much money if they shut down the game for that long to rebuild it. Financially that doesn't make any sense when the game is playable and they are making a profit. It always comes down to the bottom line.
