For some years we are expecting Google Games. The next logical step for Google. They have already introduced this new venture and have invested 100 million – 200 million in Zynga.
Google will focus on games you can play in your browser so it is logical that they partner with Zynga. Ofcourse this will have influence on the almost exclusive presence on Facebook.
Zynga is the uber king in social gaming with 1 billion in revenue and 50% of that is profit (!)
It could well be that FarmVilleChicken.com in some time will become the Google Games Community :) (if you want to).
