Does anyone know why many of Prince's repressed vinyl LP release dates have been pushed back? At first, they were releasing one every month or so and now many won't be available until next Feb2017. PLUS The Black Album has been pulled. Probate?

I am replacing the albums (vinyl) that I was too young to buy as a kid, those I originally bought as cassettes/CDs and those I've lost along the way. I've procured: For You, Prince, Dirty Mind, Controversy, 1999, Purple Rain, Around the World in a Day, Parade and Art Official Age. I'm fearful that they won't be available after Jan2017.
