The gap is likely to be around 7.7m - 7.8m at the moment. With the launch of the PS4 in China and the XB1 returning to its original price, I think the gap will grow to around 8m - 8.1m by the end of January. Then you have February when The Order (with likely bundle) is released. I think the gap will be around 8.3m - 8.4m. But I think the biggest difference in sales will be in March when Souls fans get a chance to jump on Bloodborne, which is also likely to be bundled. The accumulation of momentum from January (China launch/XB1 price rise), the release of The Order and Bloodborne will see that figure rise to 9m by the end of March.

I'm not sure what games are releasing in Japan but I seem to remember a big game? I could be wrong. If there is then I think 9m is easily doable.

Very much possible. Plus Sony will announce 20 million sold numbers very soon. I think PS4 is still undertracked here.

I didn't bother mentioning that but I believe so too.

very possible

I've been conservative about the gap in the weeks we are waiting for because I think it's possible even if the XB1 doesn't raise the price.

Dragon Quest?or Dragon Ball Xenoverse?
btw is it me or the gap has always been growing since the launch?i dont remember xbone domianting WW once...

Maybe even before. With the Launch in China and the PS4 line-up, I woudn't be surprised.

They haven't. The only reason the gap isn't 7.4m at the moment even though the PS4 sold over 200k more than the XB1, is because of 'adjustments'. I think the actual figure is around 7.4m - 7.5m at the moment, but I'm still confident the 9m is possible even without the 'possible' undertracked numbers being added.

Ever the optomist! Why not I say ... but I prefer to be less so. But when you consider I thought 18m was possible but unlikely, you could be right.

1.3m or so in 13 weeks, or 100k per week above XB1. Say 160k to 60k.

With the Chinese launch and HW spikes from new strong titles, it's very possible.

As for Japan, there are a ton of big titles that will move HW to different degrees. Bloodborne, Dragon Quest Heroes, FF Type-0, Yakuza 0, RE Revelations 2, Disgaea 5...
