So it turns out that there is solid evidence that Zenithink.com.nu forums is being checked by Zenithink officials. Just wanted to clarify any stupid posts earlier about this being a fake site. This was the first place which the 0804 firmware appeared. The representative appears to be using the alias '178655330', which is probably his QQ. I made a post earlier this morning there pointing out and error on their webpage, and it was promptly corrected on their official webpage a few hours later. So this indeed is the place to go to for all the latest ZT180 news, even though it will be in Chinese. Anyhow, good luck!
