Thanks for verifying with your friends, I'm just surprised not many people seem to be aware of these updates over here and it was out there for a bit before I decided to post it up. It's not even an insider info, just a official Q&A kind of thing.
For one it came from InArt official douyin channel so there's that. They likely will be doing these Japanese anime figures in 1/12 instead of 1/6 with the likely reasons I provided above in another post.
A bit of personal context for that reason, with 1/12 they can pivot the production channel through another factory instead of clustering them in waiting over at the 1/6 factory, causing more delays. There's also the issue that InArt is already very slow with their releases so making it 1/6 will likely kill the line up as they struggle to get more characters out of the gates, you will maybe get Denji (as it was shown) then Power or Makima? Then that's it, which is about the same as what ThreeZero has provided so far.
Think of it as Storm Toys/Collectibles where they produce figures in 1/9 or 1/12 scales and they can have a consistent output. Compared that to their 1/6 lineup and you can see why InArt may be doing the same thing.

As for whether any Chinese fans commented on it, honestly not much. I should also state that I don't hang around these forums or influencer channels much (InArt do have their own shills too) because the comments are toxic and it's either just bashing InArt delays or other brands comparison.
However, I do noticed that the Chinese fans are far more concerned with movie/IRL characters than anime characters for InArt releases, considering that some intend to complete the lineup, for eg. Joker and Batman etc.
In all, my advise is that if you are not getting the answer you want, then maybe just wait a bit and see if this news becomes official.
