With the previous Qualcomm roadmap leak mentioning two new Android devices supporting Key Lime Pie and the Google X being MIA at this year’s developer's conference—Google needs a big headliner for its upcoming I/O event.
That could very well be the official debut of the newest iteration of Android, Key Lime Pie. And since the company’s new flagship device is projected to come out within the same time frame as the upcoming OS, it only makes sense for Google to bring the two together for a huge launch.
We're sure Page and co. are thinking the same. Even if a software update follows after launch, Android's new OS is still destined to eventually come to the device.
