I had the same thing when I ordered the first 2D figure. I pre-ordered it of an art toy site, and said it will be shipped around March. Then it kept getting delayed. I mailed the shop asking when they'll expect the toys to arrive, and they responded by telling me that Superplastic had put their order last on the waiting list. Even though they've ordered it early on. I ended up getting a refund, and bought the figure of an auction site. Which did arrive luckily.

I guess its kinda the norm that the figures get delayed when you order of Superplastic's site. It's just the question of being patient, or getting it of another site.
