While the yearly top sellers show the situation since the beginning of this year, the hourly charts can show recent trends, what's happening right now.
However, don't worry, sir: I'm the first one saying that Amazon charts can give us a look to trends, but not certainties on numbers, and that they still need to be filtered, due to a core (and currently Sony) bias (i.e. core / Sony games doing better on Amazon than in reality). It's a tool that has to be used with caution.
Just add "-06" after 2014 in the address for monthly stats. Helpful.
Up, June also has a 5 week tracking period so sales could be up rather significantly.
I knew they were tracking more weeks but sales per week is really what I'm interested in. Does it increase or decrease? (I'm guessing decrease.)
