I found this comment on resetera, regarding a possible buyout:
'It makes sense. Sega has the legacy platforms for BC, a strong PC gaming presence on Windows, the missing genres needed on Xbox, a brand that still has recognition all over the world, a better chance at selling hardware in Asia, and they're affordable.'
That being said, the feel I get from the twitter pictures is that, this is more of a social visit. This subject matter (acquisition) is not something a company would allude to on social media.
