Interesting real estate prices in Dongtan; a question

Prices near Dongtan Station are incredibly expensive now, but even in the remote corners, they are around 500-600 million won, even if it's a 10-minute drive away. But even these remote areas were in the high 300 millions last year, so to think they've reached 500-600 million... Do you think even these outskirts will continue to rise simply because they are part of Dongtan?
