Microsoft's acquisition of ZeniMax Media, the parent company of Bethesda, has been some of the biggest news in gaming this week. Xbox is already heading off any speculation of more big ticket purchases, though.
Rumors of Xbox acquiring Sega have been floating around, though some of the backing seems more like speculation and red string than anything concrete. Xbox doesn't say why it specifies acquisitions, but reading the replies to either tweet will give you a pretty good guess.
After spending a hefty sum on purchasing Bethesda's many studios and properties, it'd be surprising if there were still acquisitions to announce. Xbox has picked up a notable amount of studios over the past generation, from Double Fine and Ninja Theory to Obsidian. The Bethesda deal has also come with its own quirks, as Microsoft has stated it will be honoring two timed console exclusive deals that Sony has, with Arkane's Deathloop and Tango Gameworks' Ghostwire: Tokyo, for the PS5.
Nevertheless, Microsoft CEO Satya Nadella has indicated is considering more acquisitions in the future. All of these purchases will serve to bolster Xbox Game Pass, Microsoft's subscription service.
For now, though, don't expect a big new studio to join Bethesda and the rest under the wing of Xbox. What you can expect is a show "celebrating Japanese game creators and games," with updates on Microsoft Flight Simulator for PC, a spotlight on the Japanese Minecraft community, and a review of Xbox's first and third-party announcements from the last few months. TGS kicks off September 24.
