On PC that is, with the latest Abe adventure still coming to consoles in 2020. The news broke overnight with Lorne Lanning advising that the reasoning comes down to Oddworld Inhabitants self-financing and publishing the project. An ambitious remake that made our Best of E3 2019 list, Lorne lays it out simply with "to create the version of Soulstorm we want, and you deserve, we needed additional financial assistance".

Here's the full statement as posted on the official Oddworld Twitter account.

I would like to address the entire Oddworld community (old and new). You have supported us and our artistic vision for years and we thank you.
Oddworld: Soulstorm will be coming to PC via the Epic Games store. The PC and console versions of the game will have a simultaneous release in 2020.
What I would like to do is provide you with the reasoning that went into bringing the PC version of Soulstorm to the Epic Games store as an exclusive because you deserve to know.
We've been financing Soulstorm 100% ourselves. Soulstorm is our most ambitious game ever and we are committed to creating a great game that meets the highest level of quality. But to create the version of Soulstorm we want, and you deserve, we needed additional financial assistance.
Ambition is important, and it pushes me to try and overachieve. What pushes me even more is my commitment to you: you deserve great games. As an indie publisher we must evaluate partnerships that will help up achieve our goals while protecting our vision for Soulstorm and the quintology. Epic supports our goal and commitment and is willing to help us achieve them by providing us with an advance on our PC sales, and we are incredibly grateful.
Thank you for reading.

With developer backlash at an all time high, for studios going exclusive to the Epic Games Store, no doubt an official statement like this was required. Based on what we've seen so far with the game, and how it evolves and pushes the series further than ever before, if it means the best possible version of Oddworld: Soulstorm then we're all for it.
