I do love Housman

[mme_hardy]

Her strong enchantments failing,
  Her towers of fear in wreck,
Her limbecks dried of poisons
  And the knife at her neck,

The Queen of air and darkness
  Begins to shrill and cry,
'O young man, O my slayer,
  To-morrow you shall die.'

O Queen of air and darkness,
  I think 'tis truth you say,
And I shall die to-morrow;
  But you will die to-day.

(Anybody want to expound on why it's "I shall" vs. "you will"?)

In this instance, I see the following:

The Queen uses the phrase 'To-morrow you shall die'. Even at the time the poem was written, tomorrow was usually spelled without the hyphen. The Queen, who is Fey and old, is using older language in her dialogue.

The young man's voice, or POV, if you will, is using more modern language, thus 'You will die'. However, when he echoes her direct words, he repeats her phrasing, 'to-day' and 'I shall'.

That's my read, anyway.

I think in this case white_hart has it. It's not only a usage thing but a UK usage thing.
