I'm following closely the development of three upcoming MMORPGs that are PvP-oriented. The amount of strategy features in those games is impressive : city building, structure destruction, player-driven economy, politics, territory conquest... It's like a mix between an MMO and a RTS (real-time strategy) game.
Crowfall: Medieval fantasy, somewhat sandbox. Factions (12 gods) and guilds battle each others in time-limited campaigns. Complex crafting, deep character customization, frequent change of characters, different types of maps (personal player-built maps, PvE, PvP). Estimated delivery: weeks
Camelot Unchained: Medieval fantasy, mostly sandbox. Three realms fight each other in an eternal war. Moving isles, block-by-block construction, in-depth crafting, extremely large-scale battles, non-mirrored classes, procedurally-generated maps. Estimated delivery: months
Dual Universe: Sci-fi, sandbox. Organizations cooperate and wage war to control the universe. Single shard universe with million(s) of players, multiple unique planets, player-built spaceships and buildings, voxel-based terrain. Estimated delivery: months
Soon they'll release but will keep iterating and improving after launch. For now they're in Beta and players can play regularly.
