I was just on TFSource and they have the stocking filler showing as instock and ready to ship. They also have posted brand new photos of the set including the christmas gimmicks. Here is what they say:
Happy Easter Transfans! The highly sought after 2007 WST Stocking Stuffer giftset is now instock - just in time for Easter! This set looks fantastic and inlcudes the G1 color scheme of Bombardier and an exlcusive Green Reindeer Commander - both with exclusive outfits! Instock now with limited quantities remaining, $45.95 each or $35.95 with any purchase of $75 or more! If you preordered we'll start shipping out preorders early next week!
I am so looking forward to getting these. I have ordered two of them. I hope this also means that Sludge and Swoop will be ready to be ship out as well.
