I'm wondering if the lack of prepaid gift-cards was that big of a stumbling blog to monteization of the Google Play market. If the gift-cards come out and sales surge, I'll be surprised. I think the whole industry would be totally shocked if that were the case. At the same time, I buy the Gift Cards... for various online resources, for exactly the reasons you state, Pfyearwood. Xbox Live, Club Penguin, Amazon, iTunes, those are the big ones for me. I'm sure Google Play will join the crowd.
