Season Three (which is starting on May 8th as well) will introduce seasonal Crucible rankings, private matches, the much-requested vault space increase, Heroic Strike modifiers and more.
Whether or not Warmind will be enough to win back a disgruntled Destiny 2 community though, remains to be seen.
The first Destiny 2 expansion was released previous year and was met with mixed reviews, many of which called it an empty shell.
Bungie have stated that Warmind "will send you to new places to meet new heroes and battle new enemies. You'll earn new loot and master new activities." and you will find out more during their stream showing it off on April 24th.
The start of season 3 will also bring good news for PvP fans. Over the past few months, the player base has decreased rather significantly because the "Curse of Osiris" expansion placed numerous maps behind a paywall. However, as you can see in the full roadmap - check the small print - with the arrival of Private Matches, players will need to purchase each Expansion to have exclusive access to play those Crucible maps with other players in a private match. Later in Summer, there'll be a new seasonal event as well as the introduction of Bounties and Clan chat on PC.
To bring back the excitement of playing Destiny, Bungie is rolling out weapon changes from Season 4. We also want to bring back those exciting moments when you acquire the ideal weapon. Notably, "Weapon Slot Changes" and "Weapon Randomization" are on the schedule for September, which are sure to make a lot of players happy. The item that stands out to me the most is the Gear Collections entry.
There's less than a month to go before the new content arrives, and will be part of the bigger Destiny 2 Roadmap being planned.
In addition to the announcement of Warmind, Bungie is announcing changes to Crucible.
