Destiny 2 officially announced
The art in the announcement tweet doesn’t offer a lot of concrete information, but there is enough to speculate, as the city below the tower (the main hub in Destiny) is ablaze. The city on fire could mean many things. It could mean that the enemies from the first game returned and razed the city, the traveller showed its true colour and attacked, or a house fire went out of control and destroyed the city.

Details regarding Destiny 2 will likely be revealed at E3, which runs from June 14-16 in the Los Angeles Convention Center.
