Not sure why you would think it will be discontinued. They just announced at NAMM many new colors for the St.V maybe white is gone did not pay that much attention to the old colors.
Store emailed me about the white saying they were only getting one in and it was going to be discontinued. Wasn't sure if it was the color or model or just sales talk. Lol
