From what i have seen the grills are finally made with black cloth, not the previous 2 versions with a charcoal grey cloth.
The only thing i dont like about the new version, is the shrunken down studio 60, the loss of the studio 40 and 80, and the cheesy silver plastic molding. Black molding like the ones used in the v2/3 line would have been much nicer.
Oh yeah i forgot, the big price jump for the studios. Current Studio 20 v5 costs what the 40's were before.
