This one is in via an anonymous reader. Moog Music has trademarked "GRANDMOTHER". The name is in line with the Mother-32, BFAM or Brother from Another Mother, and DFAM, Drummer from Another Mother. Moog is set to introduce the Sub-Harmonicon at this year's Moogfest.
Update: Moog One was registered as well.
Curious if either will feature what was discussed here.
