Right, I was just pointing out that for the consumer, there's basically no difference in app business models. It just may be a different payment processor and maybe lower prices.
My original point wasn't that there will be a visible difference to the consumers but that all app purchases and in-app-purchases will be structured so that Apple's cut goes to zero.
If Apple allows non-apple payment without major restrictions, it's revenue from app store will trend towards zero (save for inertia).
