At the moment I am believing the first chart, just because I dont see PS4 being just behind MS in September... at the very least it would have a good gap between the two because of Spiderman...

Yes and no. 

There is one important thing not taken into account in those charts, PS4 has something like 200 points/day (don't remember the exact number, it is somewhere in the thread) due to Spiderman preorders from previous months.

I will consider 4 scenarios for September sales 1) All numbers - previous month preorders, 2) All numbers + previous month preorders, 3) All numbers - PS4 million - previous month preorders, 4) All numbers - PS4 million + previous month preorders.

I know this is a bit difficult to follow but best method will be chosen based on NPD data and hopefully, we will have only one set of data in the future. If I had to guess right now, I would chose number 4.
