2019 Ford Focus ST: 2.3-litre EcoBoost engine confirmed?

We've seen reports the next-generation Ford Focus ST will get an adaptation of the 2.3-litre four-cylinder EcoBoost engine from the current Focus RS, and we've heard the industry chatter, but a picture posted on Facebook (above) by an eagle-eyed fan has all but confirmed it. Posted on a Ford Focus RS forum on the social media site, this image appears to come from a fourth-generation Focus ST, seemingly revealing it'll be powered by a 2.3L GTDI (gasoline turbo direct injection) engine.
