As a late backer via CrowdOx (Star Commander level), I have received Digital Reward 05 (Proliferation Cycle) and the bonus "Redemption and Malice" story, while also anticipating the new edition of Shrapnel that has apparently started to be mailed out. Digital Rewards 06-13 are naturally released when finished, but Digital Rewards 01-04 are not yet delivered.
I reckon the success of the campaign has added heaps of work for TPTB. I'd rather it be done right rather than rushed. The digital rewards are fantastic, but just the cherry on the top of some really rad models, dice, and challenge coins.
