The pre-orders are still up for Fansproject WB-002EX Core Trailer over at FPCore.com. FPCore has a limited pre-order slot for this add-on set for SteelCore. Aside from the pre-order for the Trailer, there’s also a Deluxe package that includes both the Trailer and the SteelCore figure. The purchase also includes Ruthen Core, the red figure that we’ve seen in the comics, and there are three mystery freebies together with the FPCore membership, included in the price.
