Most of the games on + already made back their development cost from their original launch. Some of them have been on the market so long that by the time they are publish on + they would retail for less than $30. Not to mention Sony is not paying publishers $60 for a game but rather a much lower price.
Add in the fact that there are no middle man (GameStop, bestbuy, FedEx, ups) which reduce the cost of a game even more for Sony.
+ is doing publishers a favor, it brings attention to games that are great, but because they have been on the market so long they no longer sell. See for yourself, when was the last time you saw a game on + chart any weekly software sales chart.
I think they easily make money +, no doubt, and the subs are growing, it pays for itself.
