Bethesda Nordic and Xbox Sweden exchanged a couple of tweets, in which they speculate that there will be an unidentified event on April 21.
Bethesda Nordic writes: "Hey Xbox Sweden, are you interested in our meeting on April 21st?". Xbox Sweden replies: "Yes, we will have fun together in Stockholm on April 21!" (the latter is an automatic translation).
Although it isn't clear what they're referring to, considering that there are no similar messages on the two firms' international and American accounts, it makes us think that it is some regional event, perhaps interesting, but not a harbinger of important news. In other words, it doesn't seem credible that the Starfield event takes place on a specific date.
It's also possible that Bethesda and Xbox have shared these tweets ahead of the main channels, and we'll update you on that soon. For the time being, we can only speculate, so we'll keep an eye on more official information.
What do you hope for? The Bethesda showcase has been announced by several sources.
