Recently it has become known that the  developers at Google have already begun work  on Android 4.0, codenamed Ice Cream. However it will still be some time before 4.0 is released, thankfully beforehand Gingerbread(Android 3.0) and Honeycomb (Android 3.5) will be released to keep our appetites quenched.

Android 4.0 will not be released until sometime in the middle of 2011.
