Based on the leaks and latest lore & comic drops, next season will be Eighth City/Kunlun vs Asgard (coming to deliver justice against Hela, which took refuge in the Eighth City).

This makes Angela (or some other prior leaked asgardian) very likely, plus a character related to Kunlun or Iron Fist lore.

This also means the season might have a mix of chinese skins and asgardian themed skins and maps.
