can you say that someone "will be getting married" as a future continuous?
I agree with Manas, it is Future Continous.
It means that someone will be in the middle of getting married;-)
I meant someone will be "in the process of getting married";-).If you are in the middle of getting married, then you are half way through the service or ceremony of marriage.
"will be getting married" is indicating a future intention of marriage.
