This tag is applied to pages that describe content to be released relatively soon.
The nuance
Knowing the unfinished nature of the project as a whole, the “upcoming content” tag can be applied to basically everything. Therefore, there is a very specific limitation: this tag only works where the content is expected to be released in a short amount of time, be it days, weeks, or a couple of months. If deadlines are specific, they’re normally mentioned in the wiki pages or in the official social media.
