it was higher... 

I wouldn't think too much about store rankings. At best they can just give a general idea of what is in demand. The difference between a few spots really doesn't matter.

its at 6th place now(game),i expected higher after the huge amount of positive press its been getting... I haven't seen it crack the top 5 yet

inFAMOUS bundle will sell more if we take the raking in Gamestop and Amazon.

The bundle hasn't even come out yet. Also there is a bundle, just not a special  edition console, Just includes the game.

If you look on all the charts, the bundle really is selling...

Being Pre-ordered.

After TitanFall.

Once Halo or Gears Comes out those are the double digit sellers which along with a massive price cut will make a major dent and get those units of shelves and into consumer hands. Furthermore people banking on Titanfall need to know so far it hasn't had much affect on sales in the past few months. The beta didn't encourage, a surge of Xbox One sales not even in the slightest a bit boost in pre-orders though which a good portion represent people who have xbox ones whom most likely bought them in anticipation of Titanfall.

Since Titanfall is coming this month i would say April is the month they "might" be sold out.
