X Factor USA: possible Season 4?

I'd say this is probably unlikely unless it's a summer series because FOX has a ton of shows on deck for next season. I can't see where they'd find the time to schedule it.
Interesting that this popped up today, because Fox are doing their upfront presentations for the next year. It doesn't seem to have been part of any of it, though.
To be 2019 they really would have needed to announce it by now.

The only thing I can think of is the UK X Factor All Stars will be international and include US acts and be shown in the US.
fgdhdhdhdh to this thread. Someone has been playing. There are 6 judges on that All Stars list above, two of which that would rather swallow cyanide than be paid to sit on the same panel as one another.
