If you really want it, I recommend you keep watching the listing as these tend to come back in stock quite randomly before the release date, be it from people changing their mind and canceling to potential restocks.
To me these Ultimate box sets are shortchanged by generally not having steelbooks as their centerpiece. I had a few of the of the JP Pixar box sets but they are little more than a cheap shoebox with a few non exclusive trinkets thrown in. Nothing compared to the BluFans special boxes.
