A leaked photo from an undisclosed Bungie event might've revealed the studio's plans for Destiny in 2015.
The presentation slide in the photograph showcases 6 Destiny milestone starting with its launch and followed by the Dark Below expansion which came out in December and House of Wolves which has already been confirmed for March release.
The slide also shows a yet-unannounced major expansion to be released in September 2015 under the moniker of "Comet: Plague of Darkness." Apparently, this expansion will be "massive" enough to be sold on disc.
After that, Bungie plans to release two more DLC packs, Vex Void and Forge of Gods. Additionally, a "Game Of The Year" edition will be released near the end of 2015, encompassing the original Destiny and all expansion packs released before the GOTY – including Comet.
The leaked photo was originally posted on Destiny's official forum but it was removed for violating the code of Conduct. Interestingly enough, Bungie removed the post without making any comments regarding its authenticity. Eventually, YouTuber LittleBigOkey crafted a high-res image of the leak. Both photos are available in the gallery.
