What happens is people read the news, tell a friend, and then the broken telephone thing happens.
Dreamcast has Windows CE on it. Dreamcast only lasted a few years. Sega announced they would go third party and be platform agnostic pretty shortly after Xbox was announced. Shenmue would be on xbox, Sonic would be on Gamecube, and Virtua Fighter would be on playstation.
To some idiot that all means Microsoft bought Sega and sold Sonic to Nintendo.
