It does sound like batches 2+3 will be coming shortly. Their SMT machine was held in customs between japan and china, so that explains why they were delayed there.
One thing that hasn't been mentioned is that Yifu stated they can produce about 50 Avalons a day once their new line is running and calibrated.
Seems strange that they imported their own SMT machine especially & then announce there will be no batch 4. Or maybe they already have the SMT lined up for sale after batch 3 is finished.
I'd thought they were independent of each other? but I really have no idea..
