sold my OG ps4 for to get a pro. advice on when to buy?

So i recently sold my ps4 to get a pro later this year. Is there any speculation on when would be best to buy it? My guess is around black friday where it will be discounted and bundled with a couple games to compete with the new xbox that is launching. Anyone have insider info or a differing prediction on when the best time and at what price a pro would be later this year?
