Domestic China Airfare - Buy now or wait?

I have been informed it is best to purchase domestic airfare in China about 8 wks or less for best prices.

I am looking at Xian to Chengdu airfare.

On ctrip.com = Right now for July 3, 2009, purchase can be made for almost 50% off - regular full fare 630CNY can be purhased for 320CNY.

Is it possible that this fare could go even lower as closer to actual departure date?

Or should I purchase now? Any disadvantages?

Appreciate any comments. Thanks.
