I'm not feeling that way, personally. They've developed all new visual and gameplay styles for the game. The graphics, while simpler than we're used to, look absolutely gorgeous. My guess would be that instead of building miles and miles of pretty but pointless background geometry and wasting processing power and money on the most technically impressive graphics as has been the norm, they're instead now focusing on visuals that are easier to created so that they can spend more time improving the gameplay. It's a trade off that doesn't feel like a trade off considering the new style looks so good.
