A reasonable price.
Sony have confirmed that the PlayStation 4 Pro will be launching this year, after all- although it will be missing its rumored October release date, shoppers and fans cans still get their hands on it this Holiday season- the Pro is going to launch on November 10.
This gives it a head start over both the NX and the Scorpio, and it also means that shoppers looking for some 4K and HDR content to go with their 4K and HDR TVs will now naturally gravitate towards the new system- not a bad place for Sony to be in. Perhaps the year head start, and the install base and content library that go with it, will let Sony fend off the Scorpio when it launches exactly a year later, then.
Sony have also confirmed that the system will be made available for $399, the same launch price as the PS4 and the upcoming PSVR.
