Thread Update:
Yesterday saw the April/June Previews catalog go on sale, which means pre-orders for #1 are now open sales-wise.
If you haven't already added the whole series to your pull list with your LCS and are ordering the issues individually now's the time to order #1.
(If you've already opted to have the whole series added then your retailer will have increased their stock level by one and your purchase will count towards sales; there's no need to order again.)
