I am wondering if there is a schedule for Android versions or devices to reach end of life some day? The term end of life refers to a state when developers decide to stop supporting a certain software version with updates. I was reading a related article on androidcentral.
So, currently Android 4.x is pretty common and rumors say 5.0 might come out in may, are there any end of life plans for any 2.x versions? I got a HTC Wildfire S with Android 2.3 and a Toshiba AC100 with Android 2.1. (Is the support bound to major version numbers or rather to devices?)
Update: I never asked at any point for speculations. I'm a software engineer and used to end-of-life or end-of-support plans. I'm am new to Android and I noticed my devices are equipped with pretty old versions, according to the link in the first comment: 3 years old, which is a pretty long term in a software life cycle (for example normal Ubuntu releases got only 18 months lifetime).
Is the support bound to major version numbers or rather to devices? Are there any end-of-life plans for Android or does that just happen if some version or devices does not get enough attention on the mobile markets? My research on this topic was not very effective. That's why I'm asking the community.
I've got no intention to seed rumors or speculations. A "no" would be a valid (but poor) answer.
