While fans anticipate this big addition, many are looking forward to more Dungeons. However, it seems like Year 5's Dungeons won't be included in The Witch Queen's standard edition. Bungie's Community Manager, Chris Shannon, clarified on Reddit they're only coming in the Deluxe Edition.

Players who purchase this Standard Edition for $39.99/ £34.99 can upgrade to the Deluxe Edition later on, letting them access the two Dungeons. Otherwise, the Deluxe Edition of The Witch Queen costs $79.99/ £69.99.
A third Dungeon is also available through Bungie's 30th Anniversary Pack. The Witch Queen package containing its Deluxe Edition and celebratory DLC costs $99.99/ £87.99, granting access to all three Dungeons for Year 5.
