the last DOAX game was made in 2006, soul calibur has put out two games since then. does it really bother you that much that one game cant get 3 sequels before another gets one?
SCVI could be another single-player/free to play adventure -_-. SCV wasn't exactly a beloved game either. DOAX3 isn't even releasing in the West.
Yeah with T7, Pokemon fighter, TxSF, etc SCVI is gonna be on the back burner for awhile. Lost Swords is ending though so take that as you will.
