I just saw this in a Kickstarter comment by Brad:

Which is just awesome! Kudos L99 Games, you're doing a great job!!
Also, there will be more promo packs on a Kickstarter campaign (expected to go live in about three weeks) for a reprint of Millennium Blades. And there will be a Promos + Stretch Goals level for all of us who already got everything Millennium Blades so far.
