Reports are surfacing like what you saw already on this site about Android 3.0 already in development. There are some pretty hefty requirements for it, too. These requirements are going to be doing some major damage to the current offering of Android devices.
Android 3.0 will feature some pretty high requirements. It will require a 1GHz processor, 512MB of RAM, and at least a 3.5-inch display. I’ve put together a list below showing all current Android devices, and the devices in bold are phones that would meet these requirements and could be upgraded to 3.0 eventually.
