Thanks for your help ! #04

Hi everyone,
I am happy to be here again and to submit my English writing.
Many thanks in advance for your help.

I would like today to explain how I understood the different ways of using the forms WILL + BE + ING.
Don't hesitate to correct my way of saying it and the grounds (explanation?) of the topic.
Every comment  is helpful !

First, it can be used when I want to talk about something I am sure that will happen in a certain time: it is planned and I precise (that word is understandable, but maybe "can pinpoint" would be better) when it will happen
"Next monday at 3PM, I will be playing tennis with Robert"
"Next week, I will be staying for three nights at  in Paris before coming back".

Second, when I want to describe one thing that will occur while another thing is already happening :
"While the children are watching the Russian World Championship (more common: the World Cup in Russia) on TV tonight, my wife and I will be eating at the restaurant"
"While my colleagues and I are working hard at the office this afternoon, our boss will be playing golf with a friend of his"

Next, when I predict or imagine something that might happen :
"The French team is so well-trained, it will be winning the cup"
"The traffic is too heavy now, you will be coming back home late"
"You can't phone him at 5PM, he will be driving home"

Finally, when I need to be polite or formal :
"Will you be sharing our lunch today ?"
"Will you be coming to the meeting this afternoon ?"
"Will you be working on this topic next week ?"

Many thanks !

Good job! : )
