The announcement of $2 billion total for App store payments to developers did not come as a surprise. On January 22nd Apple reached 10 billion total apps downloaded. From that figure and an earlier derivation of the average selling price, I estimated $2 billion was paid out around the same time frame.
We don’t know exactly how many apps have been sold at exactly the moment when $2 billion was paid out so we don’t have the means to update the ASP of apps (currently estimated at 29c).
We do know for certain however that the app store generated $2.86 billion in sales if $2 billion was paid out.
The new data affirms existing estimates.
