Bungie have released Destiny 2's summer roadmap hot on Warmind's disappointing yet pricey heels. The new roadmap shows Bungie's schedule of recycling more assets, adding a new seasonal event and a test server called Crucible Labs.
Game Director Christopher Barret and Design Lead took to Destiny Blog to lay down the roadmap for a few months ahead. The highlights of the roadmap are scheduled for September 2018, when the long awaited weapon slot and weapon randomisation changes will kick in. September bit also mentions some new game modes, and more changes that remain secret for the moment.
The picture showing the roadmap included the deployed Warmind DLC, and the next chronological step after it will be improvements to Faction Rallies, Crucible Labs introduction and Exotic Armor sandbox changes that will be coming with 29 May 2018.
Crucible Labs are a test servers where players will have access to experimental PvP content in order to give players "a louder voice" in Bungie's creative process. Players had a voice for quite a while, but it has a habit of falling on deaf ears. For example, players want proper story and less recycled content. Now, Crucible Labs is a PvP-oriented feature so implementing player feedback may be easier as changing weapon values and such does not require the amount of work new content does.
July 2018 will see the new seasonal event named Solstice of Heroes where Guardians can "celebrate their accomplishments and, of course, earn sweet new rewards". There is currently no information on how the event will be handled and if it's going to be a combined mess of microtransactions and loot boxes. This month will also bring several changes such as Expansion 1 & 2 Raid Lair Prestige, more Exotic Armor sandbox changes and Bounties coming back.
This is where Year 1 Season 3 will end, so August seems to be empty of any potential changes, with September picking up the slack later on. You can see the developers' statements on these changes as well as the full roadmap on Bungie's official site.
