Even before the the launch of the Jelly Bean, the rumours are spreading high that the successor to Jelly Bean will be named as Key Lime Pie. The Verge was quoted saying this on their website.
The current version is the Ice Cream Sandwitch released only a quarter ago which will be followed by the Jelly Bean expected in a couple of months. Google has a habit of naming different versions of Android after desserts and it looks like the company has no plans to deviate from the practice. Also, the company diligently follows the order of English alphabets.
This naming practice was adopted with Android 1.5, which was dubbed Cupcake. It was followed by Donut. Then came Eclair, which was followed by Froyo. Android 2.3 was termedGingerbread. Android 3 was named Honeycomb and Android 4 was called ICS. While there is no official report on Jelly Bean, the OS is expected be announced in the second half of this year.
Meanwhile Google is accused of launching these updates for the Media only as it takes no less than six months for the devices to get updates on their current handsets. ICS launched 4 months ago is running on around 1% of Android devices. When Google releases an updates, the manufacturers test it on their devices and then pass it on to the consumers.
