Once May 1st hits (and assuming we hit 100% funding): money will transferred to us after 3 weeks. Then it goes directly to Toy2R to put the Arghs into production. Production on those figures will take about one month, give or take, and then shipping to the US will take 3 weeks. I would anticipate we'd be able to ship the Arghs to backers in August, but of course there could be delays of a few weeks.
As far as other rewards go: I will be making the stickers and t-shirts in May. Scott will be working on prints, sketches, paintings and customs starting in May. Obviously, making prints is faster than creating all the original art. Expect rewards to start shipping in June. Some may take longer: July/August for the higher-level rewards.
Updates about ALL rewards will be sent regularly whenever I have information to share.
