Future Continuous (Future Tenses)

EXAMPLE:
Tomorrow at this time, I will be taking my English Langauge exam.
Ben won't be eating the dinner now. He usually eats it around noon.!
Will you be coming to the party tonight?

We mainly use the Future Continuous (aka Future Progressive) to indicate that we will be in the middle of doing something in a specified time in the future. There are also two other uses, listed below:

USE  

1. Future actions in progress. 

2. Guesses about the present or the future 

3. Polite questions about somebody's intentions

 Good to know

If you want to learn about somebody's intentions, you should always use the Future Continuous rather than the Present Simple. Using the Future Simple implies that you want to influence somebody's decision. Questions become much more objective if formed in the Future Continuous:

• Will you come home? (= I want you to come home)
• Will you be coming home? (= I just want to know)  

USE 1: Future actions in progress

---

The first use of the Future Continuous is to express future action in progress.

Examples:

• In an hour, I will be sitting in front of my TV.
• In the evening, I will be baking a birthday cake.

USE 2: Guesses

---

Use this tense also to make guesses about something in the present or future.

Examples:

• He won't be coming any time soon. He is still at the office.
• Beatrice will be getting married very soon.

USE 3: Questions

---

The last (but not least) use of the tense is to make polite questions about something or somebody.

Examples:

• Will you be coming home before or after 10 p.m.?
• Will you be going to the supermarket? I have something to buy.  

Form
Contracted forms
WILL = 'LL
Example: She'll have been = she will have been
WILL + NOT = WON'T
Example: She won't have been = she will not have been

Important: The Future Continuous appears in two forms: "will" form and "going to" form which can be used interchangably.
Example: "She will be dancing" means "she is going to be dancing"
