I believe Sohal, M2C and Nortrom have the potential to do it, because they have 90%+ win ratio.
However, they seem to be lacking motivation.
The top players who are actively playing, such as Desert Oasis and Constrictor have gotten pretty close with 1050 points before dropping back down. I think silver general is between 1070-1080 points.
Their win ratio is about 80-86%, just that tiny bit not good enough to make it. But keep pushing guys and eventually it might happen
