Yeah, that's possible that they'll all be made there!
I wonder though- have the Chinese companies adopted the manufacturing methods (or will) they of the Japanese. Now, I don't know a lot about Asian relations, so I could be WAY off..but I don't think the mainland Chinese are too fond of the Japanese at all....so them implementing their best practice techniques might not ever occur...
So that leads me to think that the Chinese may have cheap cars, but they'll never be made as well as GM/the Koreans cars even...that means that after an inital introduction...they'd fade out and die.
