It ALSO means we will be getting early production models. These typically have the best quality control because they were made during production ramp up not when they were pumping out thousands by the minute.
These are also the ones that get delivered early by accident on occasion. The ones from China are all held at the same place until dispatch together.
OR it could mean you have the earlier builds with problems that they didn't fix till the later builds... JK i'm sure you'll be fine
