No worries, guesswork really, who really knows DJI marketing strategies except the management there.
The other thing I feel would apply though, is they won't want to spoil the intro period, and sell refurbs when the new ones are still a novelty / new aircraft on the market.
They might bank them up, mainly to use as warranty and Care Refresh replacements, then if enough in stock, they would consider releasing a small % as refurbs for sale.
Maybe the Mini bodies are in that first stage still, using them mostly for warranty / Care Refresh replacements.
