There are some areas that would benefit with a renewal version.
The placement of the hips in battroid mode first, and second, the forward bend of the knees for gerwalk mode.
I'm among those few that don't like the the new VF-19 gerwalk mode.
I'm at my office so I don't have my VF-19 nor the YF-19 so I'm posting this pic from the net:
The leg bends "back" at a lower angle due to more forward/back movement at the ankles. It's a much more extreme and aggressive stance, better than the new VF-19 can reach.
Fighter and battroid mode of the new 1/60 VF-19 are top notch but gerwalk mode is a step back due to the poor back and forward movement at the ankles. I wish Yamato goes back to ratcheted ankles for the possible YF-19 ver 3 since it is my favorite from the 19 series.
I have the same problem, too much time between episodes. I've just watched the new one, but tomorrow I'll start all over again. It's going to be 1-4 all in a row.
