I felt better about it not being in the Amazon KoA bundle when some CAGs said the weapons pack really didn't add much to the game. Further, it was mentioned that the two other DLCs were much more important (and part of the pack sold on Amazon).

TL;DR: There's little chance of Amazon offering the Weapons pack DLC. It doesn't add much anyway, and the Teeth of Naros and Legend of Dead Kel are substantial enough. Buy it anyway
