I just don't get why Microsoft went back to the old price with the numbers looking like this. The only thing that makes sense in my head is that since Q1 is usually slow, then it doesn't matter if they don't sell that much, especially after winning Nov NPD (and likely winning Dec too), but if they really wanted to close the gap they would have stayed at US330.
Perhaps they're saving the re-drop for Holidays 2015 when Halo 5 comes out? That strategy certainly worked last time. In any case we'll have to wait until Feb NPD comes out to see if PS4 continues to build that gap or if there's any truth to the "Microsoft Momentum" theory.
Doubt it. And based on this WW sales announcement, NPD numbers alone clearly aren't telling the true sales story anyway. PS4 is selling like fire outside of NPD covered countries. And that other thread already indicates that Sony won overall through December in UK even though they lost during specific, cherry-picked moments when Microsoft declared victory.
