Well because we are still in the honeymoon and supply constrained period, and it's only been 3 months since launch, it's still possible that PS4 sales are front loaded.
But that's a moot point because either way PS4 will continue to see strong sales through to at least end of March. I figure leading up to the PS4 launch in Japan we'll see PS4>WiiU by at least 100K, so that will reduce the gap by another 300K before Japan launch. Japan launch should see PS4-WiiU>400K. So I'm thinking the VG chart for w/e 29 Feb will put PS4 ahead of WiiU.
