At this point it is inevitable. The One will not make 80M+. Not sure it will even make it past 60M, but we'll see. As for the time, I think it will happen mid-late '15. I don't think the One's holiday will be as good as the 360's, but it will help prolong the gap.
@ NiKKom
You are seriously overestimating the impact of those 2nd Tier countries. The reason MS didn't even launch in them til this late is because the 360 sold jack all in them. And that was without a much hyped and very popular PS already being available in those countries. How well do you expect the One to do now that there's a PS4 people are trying getting their hands on?
Of course, there's also the fact that the One is already unofficially available in many of those countries. Why do you think MS announced a production slow down, even though they were going to launch and more countries within a few months. I wouldn't be surprised if much of the stock going into the new countries is unsold units from other parts of EU.
