MS will be happier than Sony about the sales of the next gen no doubt about it, MS plan is never to take on and beat the others (in one shot) who have been in the console market 10 - 20 years longer than MS.
They work on long term stagedy Xbox in One or even Two generations was never meant to win outright, brand name etc takes time. The Xbox1 got the brand name in the USA = stage 1 the Xbox 360(remember only xbox 2 not even 3 i,e like PS3)
Japan = stage 2 by the time the 360 next model comes out it will have a huge library of Japanese liked games i.e rpgs already another 5 new titles have just recently been announced and there is also lost odyssey etc so if Xbox3 has the right hardware Japan will look at it more seriously. Banjo Kazoo is looking amazing will appeal to many Nintendo owners Gears of war 2 Fable 2 etc for Europe.....
Early 360 faults may of cost MS money in the short term but early PS2 done exactly the same thing to Sony with their DVD laser not loading games,grinding draw and not loading dvds unless turned upside down etc faults.......
