This is great news and I think it’s the right decision. Here is the article from TV Line.

It seems that NBC likes its Grimm foxy: Bree Turner, who plays spice shop proprietress and Fuchsbau Rosalee, has been bumped from recurring guest star to series regular, TVLine has learned exclusively.
Turner’s promotion — which goes into effect at the start of the show’s just-ordered second season — should give Grimm ample time to explore her character’s backstory, including her past as a drug addict and the fact that she comes from a family of foxlike creatures known for their sly nature. Rosalee first appeared in the “Island of Dreams” episode, when her brother, Freddy, was killed, leaving behind the lucrative-yet-shady spice shop she now runs.
Later this year, you’ll be able to see Turner — sans foxface — act alongside The Client List’s Jennifer Love Hewitt in the film adaptation of the stage comedy Jewtopia.
