I've always been suspicious of VGC numbers, and was always shocked how some people fought over how their console *won* for the week or month... only to find out it was totally different months later.
I personally think April will be a bad month all round (no major games coming out)... while May should be quite good. But I expect it to be good in PS4's favour. As others have said, if XBO cannot beat PS4 with price cuts and TF, how can it do better when that has slowed down. Even more so now that the prices are going back up in most places now.
I dont understand how this site does tracking, but it cant be that difficult to look at historical data to see which months do well/badly, taking into account NPD data and make reasonable guesses. I would also be adjusting it as soon as NPD comes in, as that would then allow better guesses for the following months data.. but it seems stuff gets changed at a later date when no one is looking :)
