People would have to stop paying for the H6 for that to happen. As long as they keep their sales, there is no reason for Sazgar to drop their margins (which I'm sure are very healthy).
Typically in China, manufacturers tend to drop prices when launching a facelift because the competition there is so severe so GWM and Sazgar have the opportunity to do that while saving face instead of getting embarrassed like KIA by being forced to drop after the fact.
