Bungie has teased the first month of events for Destiny, and the tease seems to hints at an all vehicle PVP mode and an additional to the story for the main campaign.
The Salvage mode has already been added, starting today, while it looks like a new level 26 raid will be added next week.
As you can see, after that it looks like there will be some sort of vehicle mode, which is then followed by an addition to the campaign and something called Iron Banner, whatever that could mean.
Here's the teaser image. What do you think?
