For weeks now, Bungie has been previewing new features and improvements coming to Destiny in the next update. While we still don't have a specific date for the rollout, Bungie has revealed that update 1.1.2 — the patch still doesn't have an official name — will release in April.
The update is expected to arrive before Destiny's second expansion, House of Wolves, which is slated for release sometime in the second quarter (April, May, or June) of this year.
So far, confirmed features and improvements in update 1.1.2 include a "proper Colorblind mode," more control over your game audio, and more Vault space for your precious loot. Other things mentioned, but not yet discussed include Raid fixes, changes to PvP ammo crates, and changes to Strikes. Assuming the update arrives later in April, there's a chance Bungie still could preview these.
