Thanks to a post on the Halo Waypoint Blog, we know that an update is set to arrive for Halo 4 this week. Unfortunately, no one can say when exactly, as 343 doesn't know themselves.
As said in the post: "While we'd love to give you the specific date and time you'll be prompted to download this update, unfortunately we're only given an ambiguous window in which it will release, not a hard date. So you'll know as soon as we know... or something like that, anyway."
Yaaay for ambiguity...
While the release date is up the air, it's at least known what the update will address. The blog released patch notes, which you can check out below:
Gameplay
• Reduced the range of the Boltshot’s damage scaling over distance. The previous effective range for 1-hit kills was around 20-25'. The range has been reduced to 15'.
• Fixed an issue where modified loadouts were not being saved correctly.
• Fixed an issue where attempting to sprint while crouching using “hold to crouch” would cause players to be unable to shoot for 1-1.5 seconds.
• Fixed an issue where some players were not able to get into matches on new map/game variants after playlist updates.
• Fixed a DLC-related Join-in-Progress issue that kicked players back to the title screen.

Vehicles
