This interesting post at IntoMobile is saying that 70/30 % revenue split is too low. The strange thing is that there is little to no competition between all mobile Application Stores on revenue share. Really strange, no? It’s very unusual that this is not discussed widely in the mobile industry. It would be normal to assume that all these application stores would profit from application sale volume and not from revenue share with developers.
Someone could argue that developers would go where the mobile platform offer more technical facilitators and better user experience but why not having some competition on revenue share and see what is going to happen?
If I am not mistaken in Japan the revenue split is 90/10.
