I'm not sure, even if this was true (which is being denied) what the problem is here. It's not as though paid platform exclusivity periods are anything new; they seem to be relatively common on consoles.
Perhaps this indicates yet another point of maturation for these platforms.
Are platform exclusivity agreements for iOS a common thing now for devices and applications? How many of those is Apple signing - dozens? hundreds?
It's also interesting that not even a "truckload" of cash could stop them releasing in China.
re: China sales figures, the idea that far more money can be extracted from Android users by going "free-to-play" seems to me more disturbing than encouraging. Gaming is going to seriously suck IMO if everything goes that way.
