Without a HardFork the main prediction here is that the price will skyrocket. In few months Bitcoin can be pricing $4500 or even more.
But seems things won't happen so fast, we need to wait what will happen right after August 1, maybe there will be a delay of days or weeks until things come back to the normal as we see today.
I also see this one coming. In August 1 there would be a split on mining and bitcoin itself. And with that split bitcoin is affected by that. Which makes the transaction of bitcoin faster and easier. And with that some bitcoins will not be known as bitcoin when there would be a new copy of bitcoin. Some sites will not accept the old bitcoin. But the copy of bitcoin for me is only a FUD so they can buy your bitcoins at low price. Bitcoin will probably be pumping after August 1.
