I'm personally interested in Ashes of Creation and Pantheon Rise of the Fallen. I wouldn't say "soon" though. These are also quite old school style MMOs, which I'm old and remember EQ so I'm looking forward to them.
Supposedly Blue Protocol is coming out "Soon". It's more of an anime action based MMO.
If you like skill based, janky, developed by 2 people, Project Gorgon is quite impressive imo. $45 1 time fee, and go to it. It gave me a sense of adventure, exploration, etc. It's very old-school feeling, very slow, all skill based, so you'll be doing a lot of grinding. Some folks power leveled me, but I'd recommend not doing that as you miss a lot I feel.
Someone below mention Veloren. It's totally free to play, because it's all FOSS, built on Rust. It's a lot of fun, but nowhere near complete. You can play it singleplayer or multi. You can even run your own server if you want.
