You will miss out on the discount for now
. But the shop had a black friday sale last year with every expansion at 50% off. They will probably have it this year again.
The core game is pushed back 1-3 months due to the large amount of backers, if you check out the sale this black friday you can probably buy some expansions at a better price than this KS (only dragon king and dbk is 50% off) and get them before the core game will arrive.
EDIT: I saw you live in Chile, I don´t know what the shipping cost is from the shop... if you get a good price on shipping now you might want to add some more of the most popular expansions. I don´t know to be honest.
But only the core game should keep you busy for a very long time.
