>>8366155D-Arts in general just seemed to struggle. They had a bit of a reputation for being inferior to figuarts. I remember being disappointed by the Blazblue line not getting any further than Noel.
What really kills me is the VAH Pokken line. We could have had Machamp, Gardevoir, Garchomp, Croagunk, Scizor, etc. But they went with two of the pokemon already represented by D-Arts and presumably the line flopped.
