Most people buying console had nothing to do with fan of which exclusive game(s).
And what "it's over for Microsoft", the hell?
What ? I can guaranteed you that people are getting platforms because of their exclusives as well, there is no reason to get a Xbox One over a PS4 now, especially if you don't care about exclusives...
Why do you think people still get Nintendo products if it's not for their exclusive ?
I think the Xbox brand is in a difficult position and Scorpio won't save the day if Microsoft doesn't have something to feed the console with, I'm sure the budget for the Xbox division is pretty tight right now and if Scorpio fails, I can see Microsoft taking radical decision over the Xbox brand as a console manufacturer.
