The grey model shown is of the same toy and it is actually hand crafted by sculptors (before the mold for mass release is done). This model is then photographed and digitally painted.
The sample shown is confirmed to be according to the colours chosen by the designers. While anything can happen, this seems to indeed be the final colouring of the toy.
The conversion was said to take about 15 steps (with some steps being truncated as one for this estimate).
John Warden then said that Hasbro was currently working on 160 transformers toys, at different stages of course. While that seems like a big number, it would include redecos, one steps and one step redecos.
We then got a look at how an artist designs a toy, using Soundwave as an example.
The special ended with a shot of the entire Transformers team (which seems to have as many women as men, a pleasant surprise) while an exchange of gifts were. Tmall got a custom Year of the Horse Optimus Prime while Hasbro got a 5 meter long piece of art showing many different versions of Optimus and Megatron.
You can watch the entire hour long episode here, or simply take a gander at the screenshots below. Enjoy!
Then again Voyager Grimlock had better engineering than Leader Grimlock, in my humble opinion (no partsforming and no robot hands showing).
