No manufacturer is completely committed to Android. Google themselves gave up making Android phones after the N1. Other manufacturers use it because of the Google apps included and because it's free. Google might continue the practice of making apps for non-Android phones, and port GMail Mobile and Google Maps/Earth to MeeGo. If MeeGo is fully available and free for any manufacturer to use then they will use it.

Android Market pretty much flopped and it's not worth protecting even though they get a 30% cut from all paid apps. I think we're headed in a direction that's no so app-centric. People are probably just more satisfied with the built in features in Android compared to iOS.

When it comes down to it I don't think Google cares about losing a mobile OS war at this point. They'd rather have their search engine given prominent placement as the default on every phone no matter what OS is running on it. They're probably really scared of Bing right now.
