Sadly, 'coming months' can mean almost anything short of a year.
I say this because once you hit around a year then it is hard to argue that one should not have said, (for the sake of clarity and avoiding easy misunderstandings) 'in about a year' instead of 'coming months.'
But in truth the outer limit I set forth only stands up from a basic human fairness standpoint because, in theory, December 2025 would be within the coming months, because, unless the world ends first all months in the future are, by definition, 'coming months.' That month is, after all, coming, it's just not coming soon.
