The 1.6 update adds horses to Minecraft together

 In addition to earning new texture packs  Minecraft Bukkit Plugins  and preparing to release next-gen versions from the game for the Xbox One and PS4, the developer can be working on Title Update 14 for Minecraft: Xbox 360 Edition that may add several latest features.  As reported by XBLA Fans on Feb 24, temples are one such addition hitting console versions of Minecraft with the launch of TU14.

As the name suggests,  with donkeys and mules plus horse armor and leads needed to maintain the animals and also other mobs from wandering around. One thing to bear in mind while using horse armor though is that it are only able to be within loot chests present in dungeons, Nether fortresses, abandoned mineshafts and desert temples. Hay bales are already added being a new craftable item too as you can't have horses without hay.

4J Studios in addition has revealed their desire to continually boost the overall map height and width of the Xbox One and Playstation 4 versions of Minecraft with time due to future title updates.  If the developer can manage to still improve world sizes in doing this as opposed to same menu replacement for enlarge the map will probably be used for this purpose at the same time.
