This Guinan situation was addressed a month ago by Brian Flynn from Super7. It was in a video interview available on YouTube. It was supposed to be about Thundercats but he spoke about several things, such as the state of the toy industry, production runs, and customer orders. He threw out the Guinan cancelation and the cancelation of "The Rescusers" wave of Disney Ultimates.
Super7 isn't going to cancel the line after only two waves and an incomplete crew. We still have LaForge, Dr. Crusher, Counselor Troi, and perhaps Q and Wesley at least. All easily done by switching parts. Judging by their other Ultimates lines, they will at least complete TNG and then see where or if to go from there. They're not like other companies who promise the galaxy and only deliver four or five crew members just so someone can have the unproduced figures in their private collection.
