About the system that did the software charts planning on making it publicly available?
I'll answer that one: No.
It's Brett's software, his algorithm - and no, it stays locked behind the door.
I would like to ask a question, it might be a silly one but that doesn't stop them popping into my mind, have you thought about approaching Sony for sales data that includes digital, now i'm not talking up to date sales, more along the lines of getting historical data from PS3 and PS4, and if that succeeds then convincing them to do periodic updates of Sony games since anything on a small time scale ain't happening.
Then you just have left the super easy task of getting Sony to convince 3rd parties to add their games.
I've mulled this over myself, because frankly it's just too damn easy for MS, Sony, and Nintendo to, at the very least, know and release digital sales numbers - there's no possible way on any planet, they don't have this basic information readily available... ...and yet, neither one of the three has ever been forthcoming with releasing those numbers to ANYONE. I don't know why - I don't know what the big secret is all about. But I just don't see them giving that information over to us (or anyone else) without somebody forking over $$ for the data.
