Possibly but it would have to incorporate mobile. Those consoles would have to be plugged into the internet so your mobile device could access it like a sling box. Also, I remember last year they announced a deal with a small cable operator where Zynga games would be available to play through television set top boxes (like a TiVo box). Haven't heard anything since then.
I own a PS3 and the mini-games section has grown significantly over the past few years. With regard to internet connection, the new XBox will not operate without one, which has stirred some controversy. Partnering will be key to Zynga's future if they are to be successful. Zynga could cross over into the console mini-game market very easily based on the games the currently have. I know it's not mobile and it presupposes that the console market stays strong but I am looking into the distant future.
