Sales for the PS4 and XOne are folowing the same ratio as last year PS3 and 360 at about this same months.
PS4 is doing about half the Wii numbers back in 2007-2010, they are even behind PS3 sales between 2010-2012.
Nextgen hardware sales have reached a plateau this spring and I can see nothing changing this summer. Watchdogs will give some boost but not for long.
The next great battle will be at the hollydays as usual.
