Just released in Japan, we have a good look at the Missing Link C-12 Grimlock toys colors release with in-hand views of the figure in the robot and  dinobot modes. Thanks to images from @Alfes2010, and @tagoal who also shares some notes on the figure that can you read translated below.

Transformer Missing Link Grimlock.

Compared to the original version from back then, the robot's head is positioned more forward for a more natural style. Thanks to that, it feels like this ML is less likely to give you that glitchy sensation when looking at it compared to previous ones lol.

Note that it's also possible to keep the head position exactly as in the original version; it's listed in the manual as Respect Mode. Plus, even if the head is in the forward position or the respect position, it can still transform just like that lol.

As for articulation, structurally the thighs don't lift up quite as much as you'd expect, but otherwise it moves really well. The fact that even the fingers on the hands can open and close made me chuckle a bit lol.
