Then non owners will get their cars in batches of 10k to each region starting with West Coast in order of their times pre unveil.
This cycle will continue in batches of 10k or 5k and continue to go around each region.
I find this very hard to believe, if only because actual Model 3 production plans can not be determined this far in advance. There very well may be "batches", but these numbers are likely pure speculation and should be presented to forum members as such.
