There is a bunch of MMORPGs in development and I'll focus my attention on those that promise large-scale PvP encounters, like GvG or sieges, because they're what I find most fun.
Crowfall: Somewhat sandbox, medieval fantasy. 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: Mostly sandbox, medieval fantasy. 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: Sandbox, sci-fi. 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
All the studios behind those MMOs are indie but with 10 million or more budget, so they can realize their vision without issues with money.
