For the curious, I can confirm EE is still getting the Vintage Star Wars Skiff, and it should be July/August depending on when you pre-ordered at this point. Subject to change, of course, but I just verified they are indeed still scheduled for summer.

For those concerned about your Skiff preorders from Entertainment Earth,  Adam Pawlus has confirmed that they are still safe, but warns that is subject to change (like most preorders).
