Sad news all around. I'm sure the kits will still get made but at a higher cost.
Kits will still get made at the same cost as before. Modern technology has probably reduced the cost compared to what it was in the 70'ies, or allowed a LOT more detail to be included at the same cost as back then.
The cost to the consumer might go up due to less competition in the distribution chain but this would probably only concern those who shop in the now more or less extinct local hobby shops.
