PS4 must outsell XB1 by 260,000 for break that 2 million gap.
No way PS4 wins August, and if wins September can't be by how much to cancell the August gap.
So, PS4 must beat XB1 by 260,000 in June and July, aka 130,000 at month...
Could be possible. Though i don't think will happen.
PS4 price drop in August to combat Xbox Slim and to clear stock for upcoming NEO launch for PSVR. or to increase user base for PSVR.
EDIT: also, in August, isn't it only the $399 model that is available to purchase? If so, I'm not ready to say that PS4 can't get close, if not win August. Not to mention I wonder if the average consumer will decide to wait another year to buy the Scorpio as it will be the new great thing and they only have to wait a year.
Also, to expand a bit more on my thought as to why Sony might consider a price drop:
If we really are moving away from console generations and iterative consoles with BC and forwards compatibility, Sony might roll the dice to bring as many new adopters into it's ecosystem and not let them go to MS. With that model, there won't be the huge swings we say from PS2-->Xbox 360-->PS4 user bases like we say over the last 15 years (again speculation and opinion) - not to mention the added benefit of adding even more potential customers for PSVR/PS+/PSVue/etc.
