Speaking to Computerworld, Hiroshi Lockheimer, vice president of engineering for mobile at Google, suggested Android 5.0 will launch in the fall. He stated “In general, the Android release cadence is one major release a year with some maintenance releases that are substantial still.”
Since its launch, Android 4.0 (Ice Cream Sandwich) has got just one percent of the overall Android market. It’s currently shipping on a handful of phones, with a few tablets also announced. Few existing phones or tablets have got upgrades, beyond the “Pure Google” Nexus devices (and if you have the Nexus One, you’re out of luck).
