The uses of the Future Continuous Tense

It is used:

1. For a future event, to express duration at some point in time. This is an action which starts before that time and probably continues after it. The thing that is important is the stated point in time:

What will you be doing tomorrow at 2 p.m.?

This time tomorrow, they will be travelling to France.

2. For a future event, to express its duration over a longer period:

He’ll be sleeping for the rest of his life.

3. To emphasize closeness to the present:

He’ll be sailing to America soon.

4. The future continuous can be used with a verb in the simple present tense:

When John arrives, Mary will be preparing the lunch.

Compare:

I am seeing Mary tomorrow. (arrangement)

I will be seeing Mary tomorrow . (routine action)

Also, the difference is that the present continuous tense must be always used by an adverbial of time expressing the near future:

We are seeing his parents tomorrow.

The future continuous tense, however, can be used with or without a definite time and can refer either to the near or distant future:
