Lets get this right: Upperland Studios is just a name, Rockbot is developed by mostly a single person on free time, weekends and holidays.
We never got any money from the game, by contrary, we spend a lot buying devices and licences.
So, please, do not demand we finish Rockbot 2 soon, the game comes in second place after our personal lives and is just a hobby, not a profession.
Unless someone pays me to work only on Rockbot and leave my daily job, no release dates will be given 😉
Meanwhile, you can get the beta and incomplete for the full version in out google plus community:
