Nope, I trully expect Microsoft to continue in the Videogame business, because it brought good competition and games overall, and as a gamer, i'm thankful for that ;)
I agree that they have some rough edges to smooth in terms of hardware though, I guess they'll improve vastly on this on the next generation of consoles.
Also, I wouldn't mind if Sega came back to the console world, but this time, offer a true console support instead of just offering a massive amount of add-ons that did them no good back in the Sega days, or poor games support worlwide in the Saturn and Dreamcast days.
Oh, and those who say that Nintendo dissapeared, I just want you to remind yourselves that the Videogame industry as we know it today, exists because of Nintendo, at least be thankful for that. Plus it's the most succesful videogame corporation of all time, they won't ever leave the business :)
