there is literally no way that Z4 is coming in 2 days… i’m sorry but you should get that idea right out of your head or you’re going to be very disappointed 
Pixolator said “August”, which likely means August 31st at 11:59PM Pacific time. If they were going to release it on August 1st they would’ve said “Z4 coming in July!”, that’s just the way they work… all of their timed releases have waited until the last possible moment of the last possible day.
