Its obvious he counts from 2.0 launch onwards.He and his team created 2.0 not 1.0. He took over after 1.0. 1.0 is considered another game which died now. 10 years is way too much and he is optimistic saying this. This game will look like tetris in 10 years and probably we will have newer VR MMOs in 10 years. Judging the game now he has too many things to develop to keep this game relevant. Development started to stall and we get recycled ideas over and over. They have a lot of challenges ahead. His team and his budget needs to increase if he wants to keep the game relevant the next 3-4 years let aside the 10 years he mentioned. Don't forget a huge success can easily fail afterwards if they do not maintain it somehow.
