Based on previous updates, Minecraft 1.21 will probably:

• Release on June 7th 2024

• Add a new biome

• Add a new wood type with this biome

It may also (just a feeling about these):

• Add a new mob specifically to replace poison-tipped skeletons, like strays.

• Add a new game mechanic (as in 1.19 added vibrations, 1.20 added archaeology…)

• Give the fletching table functionality

• Bring more villager changes

• Be a BIG update

• Add copper and tuff golems, as well as more uses for copper.

• Bring more redstone changes.

What do you think will come in 1.21?
