>It would be need to know what the budgets and bids are
That would defeat the purpose of a bidding system 😉
Why would I tell you what I bid? ..that would make it all too easy to outbid me and then you come out on top. As well, it would drive bids down and make it harder for Apple to profit and that's not going to make them happy.
But seeing as some devs are always looking for a way to game the system, I'd guess it's just a matter of time before bid budgets, etc. are all pushed into the light. When that happens and gets to a level that tips the scales in their favor and Apple starts to see le$$ benefit, the program will fall to the side, same as the program it replaces.
