Well, details are ridiculously scarce, but there’s a Getchu listing up for a “master groove circle 2“, due for release December 30. It has a catalogue number and everything, so it seems like a legitimate release, but there’s a slim chance this might not actually even be an I’ve release – Geneon Universal did recently add anisong juggernauts fripSide to their lineup, perhaps MGC volume 2 might be devoted to their works? One can only speculate.
