Question About the Boxes

Obviously pre-order is up, but are they going to stick around after? I want to get some, but with a pool of over 200+ cards, I can't shill out the damn near $3,000 AUD it's gonna cost for the 12 box bundle.

I'm hoping I can buy a Booster then come back for more, but I'm scared this is gonna be a one and done deal; I'd like to collect a decent amount of cards to be honest....

Any info would be appreciated!
