What I'm reading from this, is just that XBO has started "Holiday season" earlier than PS4. That's why XBO is suddenly selling way better than PS4. But I think that when those XBO bundles end and PS4 starts selling their own we'll see a similar bump like XBO, only a higher one. Seems like Microsoft caught Sony off guard this first week of November, or maybe is just that Sony is waiting for Black Friday with games like GTA V and FC4.
In the end, both consoles are going to have a very good November and that's what really matters.
