are you serious? they are doing just fine already! If you mean "how would you monetize the actual Angry Birds" then I would say they couldn't have possibly done it better than they are doing (advertisement) However, if you want to know "I have a game that is just like AB but I want to monetize it" then that is quite a different story. You need huge amounts of downloads to make money off ads, and getting huge amounts of downloads - pay OR free - on Android is a very tall order. This is basically what a lot of people are scratching their heads about. I am trying some methods right now with my own titles, so it is still early to tell, but what I am not doing is trying to sell an AB knockoff.
actually i think he answered that pretty well.... getting the numbers to support your method of monetization i feel is much harder than monetization itself.
