Patch 1.12, the "Fanon" update, is coming in 2017 and could deliver some of the content that those disappointed in 1.11 would like to see. The Woodland Dungeon is interesting for end-game players, but it's not a new biome filled with interesting new blocks and units. While maps may encourage players to get out and explore more, some fans fear 1.11 won't meet its obligation in creating new, exciting content worth looking for.
1.11 has been known as the "Exploration" update for some time and many fans built up certain expectations regarding that title. While the initial reveal of patch 1.11 was met positively, as no Minecraft fan would ever be disappointed by new content, some criticism has since followed. As for when the patch itself will be released, Mojang says 1.11's snapshot will be available as soon as Wednesday of this week, and an official change-log will accompany the snapshot's release. This is just a shortlist of changes from Minecraft's 1.11 patch featuring content shown during Minecon and does not represent the final list of changes Mojang will likely be releasing soon.
Mojang is hard at work, as ever, on the upcoming 1.11 update for the original PC version of Minecraft. Mojang is preparing to launch Minecraft's 1.11 update, which will add llamas, mansions filled with Illagers, and treasure maps, among many other changes.
