I understand I can probably get new cards with the current errata from Tournament packs, but I'm new the game and haven't purchased the initial campaign box yet. Did FFG reprint a new run of campaign box that contain these already? If yes, how would I get the campaign box I'm going to purchased will have these errata'ed cards? Thanks.

Errata is integrated into new printings and the core through most expansions already have the fixed cards.

I expect any core box you can get from a store is a new printing.
