Maybe Microsoft could publish the Xbox under Sega's name in Japan.

It will be interesting who takes 2nd spot this gen if Sega makes a few exclusives for xbox one. I can see both xbox one and switch selling 70m lifetime

and halo wars 2 was made by Creative Assembly, also SEGA

Maybe they are teaming up for some games for Xbox 2? I wouldn't be unprecedented. I mean, they even had Kinect exclusives at the beginning (even Sonic).

Sonic nuts & rings.

A joint sonic and Halo promotion. Sonic will be running around in circles on a Halo while collecting little Halos, and all of that will unlock more characters and halos to run around and collect more little Halos, thus forming an eternal and circular GaaS.

How much weight do you think Sega exclusives hold? I'm not saying the Xbox One won't reach 70 million but I don't think Sega will be in any way the reason why they would. Wii U had Sonic Lost World and Bayonetta 2 as exclusives (for the most part it's lifespan anyway), didn't seem to help it very much. Even if it's something with Atlus I don't think their biggest franchise a Persona 6 (which definitely probably won't even be on Xbox One) would cause an upswing in sales to 70 million.

Not a bad idea.

release that next xbox generation as the "Dreamcast 2" and japan would be jumpin lol

Sega sounds much more realistic than Valve, EA or Bluehoe...

Match made in heaven. Sega also got a lot of expertise in MS's core field.
