The update we are working on, TU4, is a big one with a lot of great stuff in it. We hope to have that to you soon.
Long story short. We are doing online qualifiers for the Call of Duty World League (CWL) in the middle of December. While we don't like to update the game in the middle of such an event, the CWL is just one of many influencers that make December a tough time to schedule updates for the game. It's not as easy as pulling the trigger when we want. We are organized across 3 platforms worldwide. Suffice it say, we do it all the time, but a lot goes into it each and every time with a lot of moving parts.
Thus, we decided we would hotfix (you know this as Game Settings Have Changed) as many of those changes as we could into the current version (which is update 3.)
When the actual update comes out, most of the game tuning won't change. What is in 37.25.35.4 or better will be update 4.
Here is a sample of some of the key changes that impact the gameplay directly, but not a full list of fixes and updates, which will be in the regularly in the patch notes:
