Android 2.3, codenamed Gingerbread, is expected to materialize this month. Little is known about Gingerbread's features, however, because Google develops the operating system behind closed doors and doesn't publish a roadmap. This has fueled a lot of speculation among Android enthusiasts. Google has hinted that 2.3 could bring a user interface refresh that will reduce the need for handset makers to broadly deviate from the standard user experience. Various leaks have suggested that the platform is being overhauled to boost its suitability for tablet devices. Google's new WebM multimedia format, which uses the VP8 codec, will likely be supported out of the box. It's also possible that Gingerbread will include some of the music library streaming and synchronization features that the search giant demonstrated this year at the Google I/O conference.
