Google's executive chairman and outgoing CEO, Eric Schmidt, has confirmed during his keynote speech at the Mobile World Congress in Barcelona that the Android 2.4 will combine both Gingerbread and Honeycomb.
More specifically, he said that "you can imagine the follow up will start with an I, be named after dessert, and will combine these two."
The next version of Android is widely expected to be called Ice Cream Sandwich and is already running in the wild as we've seen a few visits on ITProPortal from devices sporting the operating system.
Google has started to introduce rough six-months cycles since Eclair back in October 2009, which means that Ice Cream Sandwich should be released around the May 2010.
It makes sense to have a single Android operating system rather than two competing ones, in order to reduce fragmentation and standardise the experience for Android users.
Furthermore, Google's Sergey Brin has already confirmed back in 2009 that both Android and Chrome OS, the OTHER operating system from Google, will be merged without, back then, providing with a clear road map.
