Everyone celebrate! Amazon proven right once again for November.

OK ignore everything I said about bringing other charts into these threads. In Amazon we trust.

Also infoscout was right AND wrong. It seems Infoscout's regulars tend to favour Xbox so you have to correct for an Xbox bias in their results.

I actually did some numbers for my own consumption based in InfoScout and it panned out:

 

November 2014

Total 84% (XBO + PS4) / NPD: 2.080k
XBO = infoScout BF: 53% / NPD: 1.240k (60%)
PS4 = infoScout BF: 31% / NPD: 840k (40%)

Revised 100% (XBO + PS4) / NPD: 2.080k
XBO = infoScout BF: 63% / NPD: 1.240k (60%)
PS4 = infoScout BF: 37% / NPD: 840k (40%)



November 2015 (Predictions)

Total 83% (XBO + PS4) / NPD: 2.100k
PS4 = infoScout BF: 42%
XBO = infoScout BF: 41%

Revised 100% (XBO + PS4)
PS4 = infoScout BF: 51%
XBO = infoScout BF: 49%

Corrected 100% (XBO + PS4) / NPD: 2.000k
PS4 = infoScout BF: 54% / NPD: 1.080k
XBO = infoScout BF: 46% / NPD: 920k

Corrected 100% (XBO + PS4) / NPD: 2.500k
PS4 = infoScout BF: 54% / NPD: 1.350k
XBO = infoScout BF: 46% / NPD: 1.150k


Actual Results 100% (XBO + PS4) / NPD: 2.835k
PS4 = infoScout BF: 54% / NPD: 1.539k
XBO = infoScout BF: 46% / NPD: 1.296k

Holy crap, I had predicted a 268K gap in the November thread.

To get that, I also assumed that IS needed a correction (55/45): good call.
