Be

[JoanYY]

Excuse me,
Will you be getting any more in?

Why use be not are?

[David L.]

This is future tense. So, as a statement:
I will be getting more in next week.
He will be getting more in next week.
You will be getting more information when it comes to hand.

As a question:
Will you be getting more in next week?

or could phrase it:
Are you getting any more in?

Excuse me,
Will you be getting any more in?

Why use be not are?

Just to add a wee bit, modal verbs always take the first form/the infinitive/the dictionary form.

She might be/He may be/They should be/thou shalt be/We would be/I could be/She can be
