The second list of European countries and especially Japan are not going to make that much of a difference. At least here, nobody cares about the Xbox One anymore. It's all PS4. They're all small markets for XBox anyway. I say the release in all the other countries combined will only raise it's weekly baseline by a couple k's. Not enough to beat the 360's respective weekly sales on a regular, let alone permanent basis. Of course there's the launch itself, which maybe gives it a 100k boost that week.
I think the XBox One isn't going to beat what the 360 did in it's first non-launch holiday. However, it also won't be a million less than that so I'd say the XBox One will be able to hold it's lead it got last year until early 2015. Maybe February.
