A Brave New Geek
These promo packs are not "sets" and will not be the only way to get the promo cards, from what I understand. These cards will still be released in actual expansions later, with general distribution to stores, if you want to wait a little longer. Until then though, you can buy the promo packs through Arcane Wonders directly, but I don't think these packs will see general distribution.
Thanks man and thought so. Pupils dilated when I saw new cards!
