User blog comment:Tatsuhio Ikoma/When will f10 be released?/@comment-35850590-20181123022120

Sadly, there's no information given from the developers when Floor 10 will be released. The hypesquad cannot live off of anything except by supposedly true leaks and small responses from developers.

Long story short, nobody knows, and maybe not even the developers themselves. We can only home that it'll come soon, or even someday.
