Try to call before 8 o'clock. After that, we'll be watching the match.

- we see as new, different or temporary:
Today we're taking the bus but next week we'll be taking the train.
He'll be staying with his parents for several months while his father is in recovery.
Will you be starting work earlier with your new job?
We use the future perfect simple (will/won't have + past participle) to talk about something that will be completed before a specific time in the future.
The guests are coming at 8 p.m. I'll have finished cooking by then.
On 9 October we'll have been married for 50 years.
Will you have gone to bed when I get back?
We can use phrases like by or by the time (meaning 'at some point before') and in or in a day's time / in two months' time / in five years' time etc. (meaning 'at the end of this period') to give the time period in which the action will be completed.
I won't have written all the reports by next week.

Hello again David
The correct spelling is 'in five years' time' or 'in ten years' time'. This apostrophe indicates possession (of a sort) and it comes after the letter 's' because 'years' is plural.
All the best

Hello Harry New,
Generally, when we use will have with a by construction we consider it to refer to a time before the identified moment. However, in normal communicative use the context will determine this. It is possible that the speaker means 'before next Saturday', 'before I see you next Saturday', 'before I come to work next Saturday' etc.
