China still will dominate in most of the Opens as China has pool of talents in all departments and train hard. Just look back in recent years, which Open was not dominated by the Chinese in the final and usually Chinese took more than 3 titles out of 5 events.
Even though I kind of think MS is more up for grap but if China send Chen Yu, Chen Hong, Chen Jin, Bao Chunlai and Lin Dan to any Open, who can actually beat them? All these Chinese players are more than capable of beating Peter, Taufik, Chong Wei, Jonassen, Boonsak, ... In that sense, MS will still be dominated by the Chinese, like it or not.
