Understandably, this will upset a lot of people, many of whom are hoping to enjoy the latest Android version from Google on their Galaxy mini 2.
The Samsung Galaxy mini 2, released in March of 2012, runs on a single-core 800 MHz processor with Adreno 200 graphics, with a 3.27-inch 320 x 480 pixel display. It comes with Android 2.3 Gingerbread out of box, and unfortunately, it looks like it will stay that way.
