I think more game makers will also publish their games to their own website, Amazon Android App, and other third party App stores like 1Mobile, and not just rely on Google Play for selling their game. But, I feel there still will be many Android games which may no longer be online if Google suddenly decides to shutdown Google Play, stop selling games or unpublishing a lot of games on Google Play for some reason like how Microsoft no longer supports the Windows Phone App store, and how Blackberry no longer have an App and game store.
