Much like The Elder Scrolls VI, we didn't get much from the reveal of Starfield aside from a quick teaser trailer confirming its existence. We had some clue that this title would eventually surface due to a leak on 4chan. The post stated that Starfield would be a sci-fi open world RPG along with other details.
In the trailer, we catch a view of a planet from what may be from the inside of a space vessel. A window-like reflection of the letters "CONSTE..." faintly appears in the bottom-left corner(:17 into the video). A star-shaped station floating outside is then engulfed in light in what possibly look like some sort of hyper-jump.
Time will tell when we'll get any more information about Starfield. There is a website, Starfield.Bethesda.Net where people can watch the teaser and sign up for updates.
