Maybe, but more likely to be a sequel than another expansion.
"powbam: and this pretty much confirms GD expansions are for sure done. Even tho ive already felt that.
Zantai: I thought I’ve been pretty blunt about a possibility of a gdx3, hah. All things considered, FG did very well, but it just doesn’t make sense for the team and for the game to bloat things with a third expansion. A 10th mastery would just blow up items."
