It was only a matter of time before Bungie started to flex their independance away from Activision/Blizzard, and I'm pleased to say, in a recent blog post, they've demonstrated their studio independence. As of now, Shadowkeep will be launching on October 1, as opposed to September 17. It's only a two week delay, but it's clear that it'll allow the team to add a new layer of polish. Here's their additional house-cleaning for their new dates/details. 

• The World First for the new Raid Garden of Salvation will begin on Saturday, October 5. It’s a weekend Raid race and Contest will be active
• We’re extending Moments of Triumph through September 17 – you’ll have three more weeks to complete this year’s challenges and unlock all of the in-game and Bungie rewards
• We’re going to run an additional Iron Banner the week of September 17 as well
• Cross Save will come online later this Summer, so you’ll have time to sort out your Friend Lists well ahead of Shadowkeep

This Fall is the first step on a journey for what our team wants Destiny 2 to become - a place for you and your friends to play anytime, anywhere; owning the action MMO and RPG elements that we love about the game; and crushing barriers to entry for friends. We just need a bit of extra time to take the first step.

We didn't make this decision lightly. We know for some of you (us too), Destiny releases are events where you take time off of work or develop a sudden sickness that keeps you from school or work (we get it, a bunch of our team takes some time off to go on their own Destiny Jacket Quest). We're sorry for screwing up your plans and we wanted to share this information as quickly as we could.
