Upcoming features

1.4
Development for 1.4 has not started yet, although a statement by Cenx on the /r/terraria Discord server mentioned that the 1.4 update will have "infinite worlds". These worlds are so big, that "Traditional biome location rule" will be ignored, unlike smaller, finite worlds.

Terraria Series
Following the release of the Terraria 1.3 update, lead developer Redigit has moved on to working on another project, though developers Yoraiz0r and Skiphs plan to continue updating Terraria into the future. While Redigit worked with the team to develop 1.3.5, it is unknown if he will continue developing updates after this.

Terraria: Otherworld has been cancelled, it still has its own wiki here. Until the game's cancellation, the information on that wiki was based on spoilers released by the developers.

Redigit stated that he plans to later release Terraria 2, a separate game from the canceled Terraria: Otherworld, although little information is known about the nature or content in the upcoming sequel.
