I watched the rest of the special features on the US set, and one is indeed the video that was recently released as "out-takes", as I had suspected (I guess no one on the global fansites had watched the extras yet to mention it).

Another clip is one I recommend watching for anyone wanting to know how the current toys are designed and made... using computers and 3D printers... over a 2-3 year period. The process has certainly changed since the Hasbro tour in 2007, before 3D printers were used.
If you get this DVD/Bluray set, or if the Australian release has these extras, make sure you watch this one.

And yes, the TJ Miller (or whatever his name is) extra was really sad to watch.
