Last I checked, the videos get more likes than dislikes. Last I checked, the sales data are just from one day in a whole week of data, without counting sales from PSN.
Your point is moot, Sorry.
2 days actually. The 2 days where the games will sell the most. As for PSN - I doubt it's significant considering that the best selling PSN games sold very little.
For once, you are kind of correct. However, this is a Christmas release so you have to also factor in people who will buy it in the next few weeks as a christmas present. Also, your rule generally does apply - like 70% or something of a games sales are in the first two weeks or so. However there are exceptions, I think Borderlands (the first) was one such example.
