While it might not sound fair for the Galaxy S2 users, there is still a chance to get the latest Android 4.4 KitKat OS. CyanogenMod has created a custom KitKat ROM specifically for the Galaxy S2 GT-I9100. The ROM, CM11, is developed via the Android Open Source Project firmware.
This is great news as it means that the custom KitKat is not plagued with bloatware and comes with features like theme editing, CPU Governor and personalization choices. On top of that, it will have all the basic features of the KitKat.
