Terrible conclusion, just terrible. Your conclusion would have more strengh if XB360 was holding more customers or at least if the XB brand was holding them. But the truth is, PS4 is stealing market share.
| 2014 | 2015 | |
| XB360 | 509960 | 288300 |
| XBOne | 211420 | |
| XBTotal | 509960 | 499720 |
| XB Market % | 61.62% | 52.53% |
| PS3 | 317680 | 144150 |
| PS4 | 307520 | |
| PSTotal | 317680 | 451670 |
| PS Market % | 38.38% | 47.47% |
PS4 gained MORE customers than PS3 lost. The one solid conclusion you can get from your data is that in the generation change, customers are moving from XBox to PS. A game that was mostly enjoyed on XB is now at near 50/50 one year later. This is a tremendously successful shift for the PS brand and there is no way to spin this in a positive way for MS. 10% year on year market shifts are very relevant.
The PS4 also exceeding XB360 total sales also means that more consumers have already switched than are due to switch, further lessoning the value of "late-adopting, satisfied XB360 owners".
