Seems like the manufacturers know that the handwriting is on the wall for Android and are already starting to hedge their bets. Just read an article on PhoneDog where Sony, LG, ZTE and Huawei are all looking into the new FireFox OS.
Samsung is in heavy development with their Tizen OS and they have enough clout now that they could release the Galaxy 5 running Tizen and the average consumer wouldn't know the difference.
LG just bought WebOS (supposedly only for TV development but we'll see how long that lasts).
Also did anyone else catch the story
where the latest Chrome browser release now has the same App Launcher from Chrome OS. Eventually iPhone/Mac/Windows/WindowsPhone users will be able to download apps from the Chrome Web Store onto their devices.
Google is playing chess while everyone else is playing checkers!
