The release date for Android Key Lime Pie 5.0, has remained a total mystery to those hoping to see the big changes in the next Google OS. Though Jelly Bean 4.2 has clearly been a huge winner with Android fans, it seems to have only made the demand even higher for the next iteration of Android, Key Lime Pie. Recently, however, new rumors have emerged concerning a possible Nexus 5, which seems to point to an upcoming operating system change. Keep reading to learn more about the Nexus 5 and Android Lime Pie release date rumors.

Just this week we saw an Android 4.2.2 beta for Galaxy SIII leaked, which brings to the older Samsung phone features that have been insanely popular with Galaxy S4 users. But still, all eyes are turned to the next OS: How will it change? What new features will it bring? And will we see Android Key Lime Pie released within the 2013 year?

Though hopeful fans dreamed of the latest Google OS being announced at Google's I/O this month, the event came and went with no mention of the next Android operating system 5.0. We know Google has done an incredible overhaul of its API, bringing more cross-client integration and big changes to Google +, Google Play gaming, and more features that have been a big winner with Android fans. All this is leading some to believe perhaps instead of an OS update, Google changes are equivalent to the next big thing in Android operating systems. It is even thought Key Lime Pie 5.0 won't be the next iteration, but rather a 4.3 Jelly Bean since this system has been so popular.

Google Teases Developers With Android Key Lime Pie Hints

Before all hope is lost that a new Google Operating system is coming though, we have to keep in mind that the company did present a small glimmer of hope in the form of some videos presented at Google I/O which led some app developers to believe that Android 5.0 Key Lime Pie will be the next version of the OS.

The first clue came during Reto Meier's talk at Google I/O. Meier is the Android Development Relations Tech Lead. As he spoke to developers about what Google's vision was for their products, he showed an animation video with a little girl eating an ice cream cone on a bench. To her left sits the Android mascot with something interesting on his plate - a piece of key lime pie and a fork. The picture also features the Android mascot holding a magician hat with a rabbit in it, signifying that perhaps magic will be made in the next version for Android 5.0

The second hint came in the form of a video game screen reminiscent of a Final Fantasy-type of game screen. Bugdroid and friends are seen fighting a monster -- iOS perhaps? At the bottom of the screen we see a spell box that includes Chrome, Jelly Bean and Key Lime Pie. (To check out the video teases mentioned, watch the first hour of Google's I/O below!)

Perhaps Google was simply teasing these developers, but my feeling is, those were definite clues. It still gives us no indication if the Android Key Lime Pie is anywhere near complete or if a release date is near, but it gives us hope that someone somewhere is thinking about the next Google OS

Google Nexus 5: Rumors Point To Possible Production

Some other clues that perhaps the next Google OS 5.0 is a rumor that Sony might be working on a next-gen Nexus 5 smartphone. We know Nexus is always the first Android device to receive the latest OS so if these rumors are true, it's very possible a new OS is on the way as well.

Of course one thing to remember is the past two Nexus phones have arrived in November and December so it could still be a few months before the next Nexus 5 as well as the new Google OS 5.0.

Google Android Key Lime Pie 5.0 New Features

So what new features could we be looking at for Android Key Lime Pie when it comes? Those details are anything but clear at this point, but there's some indication we could see something like multiple apps running at the same time, a possible split screen feature and back up abilities similar to iCloud. In addition with some many kids actively using and accessing the latest mobile technology, a new Android OS 5.0 with the ability to enable a "kids mode" might be incredibly useful and a big selling point.

What features do you hope to see when Android Key Lime Pie release date comes? Do you think Google's next OS will arrive this year or later? Is Jelly Bean 4.3 what we should look for? Share your thoughts in the comments below.
