The Jungle could be turned into a Marshland/Bog once the Corruption/Crimson spreads to it, complete with unique enemies themed around those biomes. For instance, the Marshland would continue spreading with mud rather than dirt. Additionally the background gets darker there, even during daytime. A lime-yellow/chartreuse color for the corrupted grass or maroon for the Crimson counterpart. Even newer trees and flora in those biomes would be nice, such as one similiar to the weeping-willow and reeds for example.

If such new addition were to be made, that would be only plausible on mods, as the Re-Logic already have settled in the new content for the 1.4 update and, accordingly to the devs, this is probably going to be the final main update for Terraria. However, mods will be supported by the Steam Workshop, so it'll become easier to add and load mods into the client or create your own (Provided you have the knowledge on how to do so).
