So, basically, the Retail Collector's Edition is the Kickstarter CE and the Boxed Collector's Edition is the non-Kickstarter CE.
I think if you pledged during the Kickstarter, you can upgrade to the "Retail" $140 CE. Or you could until today.
So does that mean all DVD/Blu-ray's of the documentary have been replaced with a digital version + something else, or that there are two CE's with different content?
