I've heard various rumors on what the deal is going to be with ARR and HW tomes.

Couple different scenarios.

1. Only poetics and scripture will remain for old content which makes the most sense.
2. Only poetics will remain and will be used for both level 50 and 60 content.

Which is it? Was going to hoard scripture for a level 60 SAM weapon but if it's gonna have to be converted to poetics I know the exchange rate is going to be low going by track record.
