We should wait for adjustments before jumping to conclusion. If, and I mean a big if, it's true than that's a pretty horrible beating (FH2 + China + Tier 2). I don't think X1 can do anything for the global numbers, the maximum it can achieve would be an US win and won't be by a good margin.
Even that is pretty much doubtful because when Halo and Gears come PS4 may have a sizable advantage to keep momentum. November/December will be an onslaught.
I do think X1 can win some weeks after some big games like Halo or Gears, supposing they aren't matched by big releases on PS4 that could boost it too or in weeks after price cuts or good bundles.
