The REX plan on the RE: 2026 stage
On October 2, Capcom held its own technology conference, Capcom Open Conference RE: 2026, and programmer Satoshi Ishida gave the day's standout talk. According to IGN, his title said it all: the outlook and future of the REX project, meaning the evolution of the RE Engine toward the next generation. The talk describes transforming the engine through REX, a multi-step improvement project, rather than rewriting it from scratch. The long-term goal is ambitious: turning the RE Engine into an AI-generation game engine.
The three knots Ishida named
As reported by Japanese outlet GameBiz, Ishida plainly listed three problems on the development side. First, scale: games have grown so massive that even simple processes take an exorbitant time. Second, headcount: as staff numbers grow, tools everyone can easily use have become essential. Third, a sentence framed as necessity: integrating AI technology into development workflows has become an essential condition for streamlining future development. IGN writes that these three points are the justification for the REX project.
REX aims to untie these knots across efficiency, performance, tooling quality and quality assurance. According to GameBiz, the company sees gradually adding improvements to the existing infrastructure, rather than building a brand-new engine, as the right path. The striking detail IGN highlights is that at least some of the improvements are being made open-source for the purpose of training AI. Gamereactor reaches the same conclusion: the focus is speeding up and streamlining development, not generating game assets wholesale.
No AI-generated assets, AI in the process
Capcom's AI line is sharp: no AI-generated assets will be used in its games. In the March 2026 shareholder meeting statement recalled by IGN, the company announced it would proactively use AI as an efficiency tool across areas including graphics, sound and programming. Per GameBiz, REX unifies the whole engine under the world's most common programming language, making the system equally readable for human developers and AI systems. The goal sentence grows out of that unification: creating games together with AI in the future.
The backstory reaches to 2023. As GameWorldObserver writes, Capcom first introduced the REX technology, defined as the RE neXt Engine, in a video on its official R&D channel. That day's picture explains today: asset counts grew more than fivefold since Resident Evil 7, iteration slowed, the engine spread across genres, and more overseas contractors raised localization needs. In that presentation, relayed by Shacknews, the company spoke of a new level going beyond the boundaries of in-house engines.
The load of a 27-game engine
The RE Engine has quietly become Capcom's technological backbone. According to Tay Garcia of DualShockers via OpenCritic, the engine was developed in 2014, entered commercial use with Resident Evil 7 in 2017, and has since powered more than 27 Capcom titles. But after eight-plus years of continuous development, problems that cannot be solved by merely adding features have accumulated. GameWorldObserver recalls that everything from Street Fighter 6 to the latest Resident Evil games meets on the same engine; REX's gradual-evolution strategy means renewal without breaking that bond.
The timing lands in a strong year for Capcom. IGN notes the company shipped acclaimed work this year including Resident Evil Requiem, Pragmata and Onimusha: Way of the Sword, alongside screen adaptations with Zach Cregger's Resident Evil and Legendary's Street Fighter film arriving October 16, 2026. The same report carries Resident Evil producer Jun Takeuchi's words that the series advances on two tracks while remakes catch up with modern games. Per Gamereactor, the AI focus is part of keeping that intense production pace sustainable.
AI commentary
"What impresses me most is the decision to evolve the existing engine instead of writing one from scratch: carrying a 27-game legacy into the AI age without scrapping it is a bold technical and economic bet."
AI assessment
The strongest counter-view is that the AI rhetoric hides the backstage. Even though Capcom rules out AI in asset creation, process optimization affects employment too; as automation grows in testing, voice drafts or code completion, entry-level positions may narrow. IGN's consumer-press perspective does not ask this question; the goal of creating games together with AI leaves open who creates how much.
Gaps are also worth noting. The GameBiz account carries no schedule: when REX's stages will land is unclear. The open-source step IGN reports is exciting, but which tools will open and under what license is undisclosed. Nor is it known what was tried during the three silent years between GameWorldObserver's 2023 framework and today's talk; only the roadmap is presented, failed prototypes are not.
Source positions should be weighed. IGN and Gamereactor are player press; they report the development as product and industry news without technical audit. GameBiz, as Japanese trade press, relays the company presentation directly but does not independently test Capcom's claims. GameWorldObserver with Shacknews, and DualShockers via OpenCritic, are specialist outlets; they build the historical context but rarely step outside the presentation material.
The practical takeaway: engine competition is shifting from frame rates to production-line efficiency. If REX succeeds, Capcom becomes a rare example of carrying an existing engine into the AI age without scrapping it. The metrics to watch are clear: the scope of the open-source promise and developer feedback on unification under the world's most common language. If both hold, the slogan of creating with AI gains flesh and bone.
