I suspect we will have some turmoil at the start of August. There will be wild swings in the price and two chains will appear. Core/UASF supporters will claim "the other side" has failed to honour something-something-lots-of-handwaving, and once Segwit is locked in many miners will switch back to a recent version of Core, thereby blocking the miserable 2MB increase that is a waste of time. A brief battle will ensue, followed by a big block chain becmoing dominant. Sustained DDoS attacks will begin causing more uncertainty in the market. Blockstream will accuse $ENEMIES_OF_CARLOTTA of blocking bitcoin's growth, and we all know the SOP from here.
