It has been confirmed that both Xbox and Bethesda are set to make an appearance at Gamescom 2023 in Cologne, Germany, with more information coming soon.

The details:

The attendance was confirmed by Gamescom's official Twitter account, marking another year that the gaming giant has attended the show since its inception in 2009. With Bethesda also present, it's likely that Starfield will be the main attraction of Microsoft's presence, potentially allowing fans to get their hands on the game early.
We might see a new announcement from the company at the show, but after its two-part showing at Summer Game Fest last month, it's more likely that it will expand on what we already know about its upcoming titles like Fable, Forza Motorsport, Avowed, and even third-party offerings like Persona 3: Reload. The trade show frequently features playable demos at attendees' booths, so fans may get to try out some of the most anticipated games before the final build, and those same demos may also be released via the Xbox and Windows stores around the same time.
Despite rumors that it had pulled out of E3 after claiming that it "doesn't have enough major releases ready to show that would justify significant event space,” Nintendo was the first attendee to be confirmed for Gamescom. Sony, on the other hand, has not confirmed its attendance, and, like its appearances at E3, it has not attended Gamescom since 2019, instead opting to host its own online showcase, State of Play, to announce new releases.

More Microsoft news:

Multiple key developers from the original Banjo-Kazooie development team have stated that a series revival is unlikely anytime soon due to concerns about the size of its potential audience. Grant Kirkhope, the series' composer, believes that the fanbase exists in a "bubble," and it's difficult to predict how large the player base would be outside of that.
Larian Studios has confirmed that an Xbox port of Baldur's Gate 3 is still in the works, but that "compromises" may be required to ensure a final release. This is due to Microsoft's policy of requiring all games released on the Xbox Series S to share the same features as the Series X versions of the game, forcing developers to find a way to get the game's co-op mode to run at a suitable level of performance before launch.
