It would not surprise me if Ford continues the current Taurus in the US and has the Chinese version just for the Chinese market. That is contrary to the "one Ford" strategy that they have talked about but there is just not much evidence that we will get the Chinese version here.
It is a pretty safe bet that the Police Interceptor will continue on the current platform and be built in Chicago so it makes some sense that the civilian version remain on the same platform.
I really would like to see the Chinese version here, though, along with an SHO version of course.
