With Dungeons & Dragons' Dragon Heist adventure on the horizon in September, followed shortly by their November release of the Guildmaster's Guide to Ravnica, it seems that adventuring parties from around the world will be leaving the far reaches of Faerun in favor of that good, good urban life!

While Dragon Heist is set to feature a deep dive into Waterdhavian society, Guildmaster's Guide to Ravnica ups the ante by crossing the streams with Wizards of the Coast legend Magic: The Gathering for the first time and allowing heroes to explore the fan favorite world spanning urban sprawl of Ravnica. 

With the huge surge in popularity of D&D and Magic’s commitment to bring the lore and storytelling to life, the timing seemed perfect. Ravnica is full of adventure possibilities and I can’t wait for fans to jump in to embody a member of one the iconic guilds. I will personally be making a new character for Rakdos.
— Nathan Stewart, director of D&D

In perfect synergy, Magic the Gathering is set to release the Guilds of Ravnica set for the TCG which promises to create a great bridge for fans of both games to deep dive into lore and experience new game play. Wizards of the Coast also teased that we may be visiting other Planes in 2019 so this is likely the first of many collaborations between these powerhouse design teams.

In addition, fans of the Eberron campaign setting will be delighted to note that the Wayfinders Guide to Eberron is available now via the Dungeon Master's Guild as it is updated by Keith Baker, the original writer, and the Dungeons & Dragons team. For those new to the Eberron setting, it features a magic-heavy, fantasy noir vibe with undertones of Steampunk. It boasts classes like the Artificer, best known for creating magical items and drafts as a control/support class, and races like Changelings - a player friendly version of the Doppleganger monster - and Warforged - large sentient constructs molded by magic. 

It’s been sixteen years since I planted the first seeds that would become Eberron, and watching it grow has been an amazing journey. So many good people have been involved in creating the world we see today, and it’s been wonderful to see it come to life. I can’t wait to see what people do with the world!
— Keith Baker, creator of the Eberron setting.

They will be adapting the setting for 5th edition with all sorts of "adjusted races, dragon marks, new backgrounds and more" according to D&D site. My guess would be that we are likely to see a hardcover book release in the future, but for now we'll have to be patient.
