Seems like a nasty habit to have!

Are they actually releasing data?

This should be interesting.

Well it's official PS4 sold more consoles, Xbox had more revenue.

PS4 > XB1 in units
XB1 > PS4 in $

Both the PS4 and XB1 also had their best months in units this generation. If I'm right that means PS4 > 1582k and XB1 > 1511k

Edit: Article got updated to say XB1 didn't have it's best month, but best November. So XB1 > 1296k (seeing some people say >1376k, but from what I can find that was December 2015)

So, now it is officially confirmed that PS4 stole this month

Some more precise estimates:

PS4 > 1.582m (up 40% YoY and best month ever)
XBO > 1.376m (up 40% YoY and best November ever)
