Because Kato no longer takes pre orders from dealers the second delivery is need to fill orders. Kato only announces a model after production has begun. So after the original run is sold out they have a second if orders still need to be filled. Say Kato stock run is 1000 pieces (i don't know the real number) they give there dealers 2 months to order and first delivery is 3-4 months form the announcement. If they get 1500 orders then a second run is needed and that is what the second delivery is.
