Leaks from earlier in the day suggested that an official Destiny 2 reveal was incoming, but instead, Bungie's dropped a launch trailer for the Age of Triumph event, which goes live in the original Destiny on the 28th March. Bah!
Still, it's a pretty rousing trailer. The Age of Triumph sees the return of past Raids with new rewards, and will basically act as the first game's last hurrah before the inevitable tidal wave of Destiny 2 hype comes crashing down on us.
In any case, that official announcement can't be far off if promotional posters are in circulation. We recommend staying tuned.
