Do you mean the player or NPC models?
There are plenty of NPC stuff here such as Violet's 3D model, sexy female mages and warriors, new look undead like scary zombie monkeys with scorpion tails, and characters that don't seem to be in the game currently like High Diviners.

If you mean new model for player, or the World Guardian, I don't think there is any yet but some survey information suggested Jagex is working on characters with Classes. If there are character classes, undoubtedly there will be different character models, only that we don't know if the new model will be in Jagex's current games.
