It is not just the weapons, armor pieces, and the sandbox that will see tweaks in Destiny 2's newest expansion. It is set to bring massive changes to the vendor department as well. Players will find new rewards from almost every vendor in the game, be it the Focusing gear pieces or the reputation rank-up rewards.
This article lists every vendor change coming with The Edge of Fate expansion.
Destiny 2: The Edge of Fate vendor changes
Here are all the changes being implemented for vendors with the start of The Edge of Fate expansion:
Xur

The agent of the Nine will NOT be selling Legendary armor pieces anymore. Instead, players can get these pieces from Ada-1. Xur will now sell two Exotic armor pieces rather than one for each class, every week. These armor pieces will include the Legacy ones that he always sold and a newer expansion from The Witch Queen and The Final Shape, among others.
Regarding weapons, Xur will sell nine Legendary weapons, and Brave weapons as well. There will also be a chance for an Adept weapon to show up alongside weapons from the Episodes.
Currencies such as Strange Coins, Ritual Engrams, and upgrade modules will no longer be sold by Xur.
Ada-1

Ada-1 will offer 20 Threader bounties per week and Legacy Legendary armor pieces. She will also grant older players free tokens to spend on Exotic armor pieces.
Her bounties will also be reworked with The Edge of Fate, where PvE bounties require any destination, and PvP bounties require any mode.
Banshee-44

The gunsmith will not have a reputation system going forward. Furthermore, upgrade modules and Gunsmith Engrams will be removed from his shop.
Rahool

The Cryptarch will also follow the steps of his neighbor on the Tower, and will not have a reputation system. New armor pieces can be obtained via the Legendary campaign instead of Rahool's inventory.
